splits on spaces also considers \r\n\f\v\t as mandatory breaks
I'm still working on the strptokspn function
my goal is to use it directly rather than storing the matched char
and modifying the source string with \0 in order to tokenize the output

Several places in the codebase implemented an ad-hoc form of pinning;
they can be converted to use buflib pinning instead.

This gets the volume that the path eventually refers to by parsing
the last volume specifier and returning the part of the path after
it (which does not contain any volume specifiers). The initial part
of the path therefore contains everything up to and including the
last volume specifier.

Searching in volume 0 is necessary for multiboot targets with only
one drive, like the M3K/Q1/ErosQ. Without this the search code will
never look at the redirect file on these targets.
The search bound is configured with a setting MULTIBOOT_MIN_VOLUME,
which defaults to 0, but is defined to 1 for Sansa players so they
keep their old behavior.

The implementation of write_bootdata() and get_redirect_dir() was
copied verbatim in two different places, obviously a bad thing for
maintainability. This moves them to a new file multiboot.c as they
are only used for multiboot.

Helper for another semi-typical operation: find out how big of a
buffer should be allocated before decompressing. This can be useful
when the stream container doesn't specify the decompressed size.

Using an in-memory buffer for the input or output data for 'inflate'
is likely to be extremely common and there's really only one way to
do it, so predefined helpers should be provided.

Loads external drive into root namespace
Root Redirects can now be put into different folders

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.

There are various allocations that can't be moved or shrunk.
Provide a global callback struct for this use case instead of
making each caller declare its own dummy struct.
Also fixed ROLO and x1000 installer code which incorrectly
used movable allocations.

guard file_cache_reset as well

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.

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()
