Gate buflib_get_data() checking, debug printing, and buflib
integrity checks behind individual defines in buflib.h, and
turn them all off by default. If needed, they can be turned
on manually when compiling.
The buflib debug menu is only available if debug printing is
enabled, so after this commit it will no longer be included
in normal builds -- it isn't very useful to end users.

Removing the variable-length name in the middle of buflib metadata
makes it a lot easier to deal with.
Change-Id: I6eaf236c2285cae40fb6ff0fa5acf827972cdd8b
The CRC is a fairly useless safety check because we already
have specific checks to validate the metadata, and CRCs are
only verified before calling the move callback. Removing the
check should not significantly reduce buflib's robustness.

Remove the name handling code, but leave the allocation structure
otherwise untouched; it's as if all callers provided a NULL name.
The public API still accepts names but names are no longer stored
or returned.

Naming your allocations is more of a debugging feature; it's a
bad idea to abuse this feature for storing some random string.
The font code does exactly that to remember the path used to
load a font, and it's the only code that uses buflib names in
this way.
Store the path inside the font allocation instead as a regular
char array. For simplicity it's MAX_PATH sized, so this'll use
a bit more memory than the buflib name method, maybe 1-2 KiB if
a few fonts are loaded.

It's usually only called from init() in main.c, so this is safe.
There is one more call in system-dm320.c from system_init(), but
that's also "safe". I don't know if it's okay to call i2c_init()
twice, but presumably it works...

On single-core targets, system_init() is only called from init()
in main.c, which is also INIT_ATTR, so this is safe.
Multi-core targets additionally call system_init() from cop_main(),
which isn't marked INIT_ATTR. I'm fairly certain that it would be
safe to add INIT_ATTR to cop_main() with a bit of refactoring, but
I don't have a way of testing it. So for now, leave INIT_ATTR off
for multi-core targets.

chunk_alloc allows arrays (or any data) to be allocated in smaller chunks
you have to save the indices..
variable data will have variable indices you need to
store these as [chunk_alloc] doesn't keep track
if you have a fixed size for each
alloc you can do indice / sizeof(data)
or index * sizeof(data) to convert
Lots of debug stuff still in and it needs optimization
User provides chunk_size and max_chunks
max_chunks * struct chunk will be allocated at start
with (1) chunk_size allocation initially
alloc_chunk() with size = 0 shrinks the last allocation to the size of the data used
add OOM checks on buflib_alloc -- oops
move bytes available to the header -- less memory per chunk & better alignment
keep track of the current in use chunk index -- should speed things up a bit
Now allows:
realloc chunk header
larger allocations than chunk size
reallocs smaller than existing will shrink the current array
rather than alloc a new and copy data
Comments welcome :)

The font code expects the full path to be stored in the
buflib alloc so this breaks eg. saving the glyph cache.

HAVE_MULTIVOLUME is a subset of HAVE_MULTIDRIVE
in normal circumstances they are interchangable
but when the internal drive is not found the assumption falls apart
at the moment most of the bootloader are less selective about what drives/volumes
they will mount therefore the volume might not match between what the bootloader
returns for multiboot and what the firmware sees
updating bootloaders will fix this but it should probably be made more robust
at the same time

This flash chip is found on some Surfans F20 units. For our purposes
it's the same as the GD5F1GA4xExx so just #define an alias instead of
adding a whole new chip struct.

replace applicable calls to strlcpy with calls to strmemccpy
which null terminates on truncation
in theory the strmemccpy calls should be slightly faster since they
don't traverse the rest of the source string on truncation
but I seriously doubt there is too much of that going on in the code base
