This adds an adapted version of the adler32 algorithm from tinf/zlib
which will be necessary to support ZLIB deflate streams in the future.

This relies on a macro, CRC32R_FAST, to select which version to
compile with. In tests the fast version is 2x faster at the expense
of requiring 960 more bytes for the lookup table. For now the default
is the space optimized version but in the future I would like to enable
this for ports where we can afford the extra storage and/or memory
requirements.

This adds code sufficient to extract files to available storage given a
suitable root directory to extract to. It works on an already open zip
handle and also supports chain-loading a secondary callback in the event
that integration into the process is desired.

This eliminates the dependence on a special struct since we were only
using the modtime anyway. But it no longer fits any known standard APIs
so I have converted it to our own extension instead. This can still be
adapted to existing hosted APIs if the need arises.

This emulates the traditional utime function from UNIX clones to allow
for manual updates of the modification timestamp on files and directories.
This should only prove useful for non-native targets as those usually
have a libc version of utime.

This does the opposite of dostime_mktime, converting time_t back to
the two dos date time values. We use gmtime_r for native because that
is what is available and acts the same as localtime_r on other platforms
with a regular libc available.

This provides rudimentary support for parsing the contents of a ZIP
file. For now this just supports uncompressed file entries but DEFLATE
support is planned. This also only implements a low level public API
so more work will be needed to make it usable by application code.

This moves the time conversion function to timefuncs since it has
uses on ports that don't use the FAT driver. This function has no
dependency on the FAT driver as it is so this should not cause any
issues. To reflect this separation the function was renamed to
dostime_mktime since it is really for DOS timestamps. The places
where it was used have also been updated.

This uses an equivalent algorithm but with a different initial value
than we normally use (all bits off vs all bits on). Use the new crc_32r
to replace the original MI4 crc32 implementation.
This frees up some extra space on mi4 targets which gives us more
room on a few very space constrained targets (sansa c200/e200, etc).
Change-Id: Iaaac3ae353b30566156b1404cbf31ca32926203d
This uses the reverse of the polynomial used by the current crc_32
function. The code for this was derived from the implementation used
by tinf. This version is space optimized and should be a good way to
reduce code duplication in other parts of rockbox that use the same
crc32 algorithm. This is mainly of use in areas where DEFLATE is in
use.

Needed for g#3415, and if the comment is to be believed, this needed
updating for recent MIPS targets anyway.
Just blanket enable everything for all targets with >= 8 MiB of RAM.
The only targets with less than this are the Sansa Clip, c200v2, and
m200v4, which all have 2 MB of RAM.
The added code size is around 4 KiB to 7 KiB, depending on the target.

Before this was just implemented inline wherever it was needed. Now
it is provided as 2 inline functions in a header called checksum.h.
There should be no differences in actual behavior.

Firmware now includes rudimentary redirect functionality
but this only supports /.rockbox in the root of the device
This patch allows loading external drive and directory into root namespace
Root Redirects can now be put into different folders
For instance placing '/_test' into SD1/rockbox_main.<playername>
will redirect to /<1>/_test/.rockbox
Debug menu>Bootdata now has root directory listed in addition to RAW Bootdata
Redirect root work from Michael Sevakis g#1556
Redirect will be updated if code refactor is ever done
Requires Multiboot bootloader (already in main)

Provide definitions for the macros:
* RB_ROOT_VOL_HIDDEN(v) to exclude certain items from the root.
* RB_ROOT_CONTENTS to return a string with the name of the
directory to mount in the root.
Defaults are in export/rbpaths.h
It's a bit much for those that don't need the full functionality.
Some conditional define can cut it back a lot to cut out things only
needed if alternate root mounts are required. I'm just not bothering
yet. The basic concept would be applied to all targets to keep file
code from forking too much.

I never added multiboot awareness to ROLO
When a new firmware file was loaded [Bootdata] would not be
copied to the new instance resulting in the firmware
running off the internal drive till next reboot
Bootloaders shares the rb-loader code but should not be
affected by the removal of static from write_bootdata()

Instead of only mounting partitions with a FAT partition type, try any
partition that isn't type 0 (unallocated) or 5 (extended). This makes it easier
to reformat SDXC cards which have the exFAT partition type, and also brings us
in line with pretty much every other OS at this point. Anything with a
valid-looking FAT superblock will get mounted.

Stop gap till I get a chance to work on the root folder stuff
Makes whatever volume marked by bootdata.boot_volume
the base or root volume, mounts all other volumes after
the specified boot volume.
Has the effect of swapping the SD card to the slot for internal
and Internal storage is mounted as the Sd-card.
Does not honor root redirect -- uses .rockbox folder in the root of boot volume

The Quake plugin is the only code that actually relies on float
formatting. Because Quake only runs on targets with huge memory
anyway, limiting their formatting to just those targets will minimize
the increased memory use in the core.

Wanted to see how gnarly it is to do.
Big number handling could be done with better algorithms
since it can get a bit slow with large integers or tiny
fractions with many lead zeros when only a few digits are
needed.
Anyway, it supports %e, %E, %f, %F, %g and %G. No %a or long
double support seems warranted at the moment.
Assumes IEEE 754 double format but it's laid out to be able to
replace a function to handle others if needed.
Tested in a driver program that has a duplicate vuprintf and
the content was pasted in once it looked sound enough to put
up a patch.

when precision is not specified memchr recieved -1 for count
count is unsigned so it looks in a potentially very large area
for a terminator and returns this whole area if \0 is not found
Instead we should use memchr when precision is specified
and if precision is not specified use strlen

is_diacritic is used for pretty much all of the text display sizing
Timing here matters, so important it uses a
priority buffer in order to cut down on searching the database.
This patch is verified functionally equlivalent but
saves 80 bytes and is ~20% faster for the clip+ I tested it on
Several things were done:
Optimizing the copy loop for the priority buffer
Globbing some operations together
but the main one has to do with the database structure its self
--
Rather than a bit packed struct it combines the lower 8 bytes into
one value [info] and uses flags to access the values instead

most of the potential.

Instead of checking ticks, set a sticky dirty flag that indicates
that the RTC needs to be read. This gives a timely update and more
accurate readout without actually reading the RTC until it changes.
The implementation should atomically read the flag and clear it.
Setting the flag would typically happen in an RTC tick ISR.

New support as well as some buggy support fixed.
Still no floating point support if ever that would be desired.
Support (*):
* Flags: '-', '+', ' ', '#', '0'
* Width and precision: 'n', '.n', '*' and '.*'
* Length modifiers: 'hh', 'h', 'j', 'l', 'll', 't', 'z'
* Radix: 'c', 'd', 'i', 'n', 'o', 'p/P', 's', 'u', 'x/X'
(*) Provision exists to switch lesser-used stuff on or off or when
certain functionality isn't desired (bootloader?). The compulsory
radixes are everything but 'o', 'n', 'p/P' and 'x/X' with length
modifiers being optional. The default setup is 'l', 'z', 'c', 'd',
'p/P', 's', 'u', 'x/X'.
* Move fdprintf() to its own file. It was in a strange place.
* Make callers compatible and fix a couple snprintf() bugs while
at it.
Could smush it down in size but I'm gonna get over the binsize
neurosis and just the let optimizer do its thing.

Adds the ability to load firmware from other drives on MULTIVOLUME targets
Mihail Zenkov <mihail.zenkov@gmail.com> had posted a hard coded patch
to allow this on several Sansa players, I made it more universal
Redirect file rockbox_main.<name> should placed in root of
drive you would like to be main, if this file empty or there a single
slash '/' firmware will be loaded from /.rockbox in root of this drive
If instead a /<*DIRECTORY*> is supplied in rockbox_main.<name> then
firmware will be loaded from /<dir>/.rockbox/
NOTES*
The directory can have multiple levels however..
leading slash MUST be included
trailing slash can be omitted
(eg. /test/.rockbox would be simply '/test' in the redirect file)
Redirect file will not work on internal drive (whatever is default boot drive)
Volume with the highest index containing redirect file will be loaded
first.
Firmware file is checked for boot data region, if missing, firmware
image will not be loaded.
On failure or if no redirect file is found load will fallback to
internal drive
Currently only Sansa Fuze+, Sansa Clip+,
Sansa Clip Zip, Sansa Fuzev2, and Sansa Fuzev1 are implemented.
Players (with HAVE_MULTIVOLUME)
will need #define HAVE_BOOTDATA and #define BOOT_REDIR "rockbox_main.<name>"
added to their config file
boot_data is implemented in crt0.s file (See g#1552)
ARM and IMX233 have aleady been implemented
Once these conditions are met <HAVE_MULTIBOOT> will be defined by config.h
Partitions on the drives are able to have a redirect as
well.
