Rocklua was using the full fscanf implementation
to simply read %ld for the file:read("*n") function
wasting 1k on unneeded/unused functionality
Instead, I've implemented a filetol function to duplicate it
without the extra overhead using strtol which as an added bonus
ERANGE errors now resolve to LONG_MIN and LONGMAX instead of
integer overflow
filetol()
reads long int from an open file, skips preceding
whitespaces returns -1 if error, 1 on success.
*num set to LONG_MAX or LONG_MIN on overflow.
If number of digits is > than LUAI_MAXNUMBER2STR
filepointer will continue till the next non digit
but buffer will stop being filled with characters.
Preceding zero is ignored.

FILE typedef to *void needs more work to not break sim and
application builds. I checked only a few random native builds
unfortunately. Sorry for inconvenience.

Prior to this patch the Lua plugin used version 5.1.4. This change
reduces the number of modifications in the Lua source using some new
defines and because the upstream source is now more flexible.
Unless otherwise stated, l*.[ch] files are taken unmodified from the
upstream lua-5.2.3.
fscanf.c:
file descriptors in rockbox are just ints, they are hidden behind a
void* now so liolib requires less modifications. fscanf is updated to
use void* too.
getc.c: this is a new file required for getc implementation in lauxlib.c
lauxlib.c: LoadF replaced FILE* with int, the rockbox file
descriptor int are cast to FILE* (actually void* due to typedef).
getc uses the PREFIX version. stdin is not used, as per 5.1.4.
lbaselib.c: now uses strspn in the number parsing. print uses DEBUGF now
rather than being commented out.
lbitlib.c: use the built-in version from 5.2.3 rather than Reuben
Thomas's external library. Backwards compatible and adds some new bit
operations.
ldo.c: the LUAI_THROW/TRY defines are now in the core lua code, so have
been removed from rockconf.h
liolib.c: here the implementation has changed to use the LStream from
the original source, and cast the FILE* pointers to int. This has
reduced the number of modifications from the upstream version.
llex.c: the only change from upstream is to remove the locale include.
lmathlib.c: updated from the 5.2.3 version and re-applied the changes
that were made vs 5.1.4 for random numbers and to remove unsupported
float functions.
loadlib.c: upstream version, with the 5.1.4 changes for missing
functions.
lobject.c: upstream version, with ctype.h added and sprintf changed to
snprintf.
loslib.c: upstream version with locale.h removed and 5.1.4 changes for
unsupportable functions.
lstrlib.c: sprintf changed to snprintf.
ltable.c: upstream with the hashnum function from 5.1.4 to avoid frexp
in luai_hashnum.
luaconf.h: updated to 5.2.3 version, restored relevant parts from the
original 5.1.4 configuration. The COMPAT defines that are no longer
available are not included.
lundump.c: VERSION macro conflicts with the core Rockbox equivalent.
rocklib.c: luaL_reg is no longer available, replaced by luaL_Reg
equivalent. Moved checkboolean/optboolean functions to this file and out
of core lua files. luaL_getn is no longer available, replaced by
luaL_rawlen. luaL_register is deprecated, use the newlib/setfuncs
replacements. rli_init has to be called before setting up the newlib to
avoid overwriting the rb table.
rocklib_aux.pl: use rli_checkboolean from rocklib.c.
rocklua.c: new default bits library used, update the library loading
code with idiomatic 5.2 code.
strcspn.c: no longer needed, but strspn.c is required for strspn in
lbaselib.c

Instead of providing yet another memory allocator implementation
use tlsf and simply link tlsf library.
Another small improvement is to *grow* memory pool by grabbing
audiobuffer instead of just switching to use audiobuf exclusively.
Tested with simple lua 'memory eater' script.
This patch extends tlsf lib slightly. You can provide
void *get_new_area(size_t * size) function which will override
weak dummy implementation provided in lib itself. This allows to
automaticaly initialize memory pool as well as grow memory
pool if needed (for example grab audiobuffer when pluginbuffer
is exhaused).
