The name blobtool is confusing as 'blob' is also used to
describe nonfree software in binary form.
Since this utility deals with binary configurations it
makes more sense to call it bincfg.

Because of how blobtool works, we need different files for the 128 and
256 byte versions.

NR indicates the last non empty region, which in this case is
GbE (region3). Needed for flashrom ifd layout support.

- Rewrite STRING and COMMENT expressions to remove need for CHARS.
- Clean up regular expressions - get rid of unnecessary expressions.
- Remove extra newline from the end of the file.
- Clean up stripquotes() function
-- Remove unnecessary backslashes in '\"'
-- Check malloc for failure
-- Remove unnecessary assignment of 0 to the end of the new string,
snprintf will take care of it.
- Update blobtool.lex.c_shipped to the new version.

blobtool uses the same sort of update mechanism for the .l & .y files,
so update the SCONFIG_GENPARSER Kconfig question to encompass both
utilities.
- Change the name to UTIL_GENPARSER, and update the help text.
- Update sconfig's makefile.
- Add the check to blobtool's makefile.
- Update the makefiles to check for y, not defined.

Add a Makefile.inc, based on sconfig's, to use the _shipped variants
so that the build doesn't have to generate them with flex & bison.
The GENPARSER check is inactive, and will be updated in the next
commit.
Add the c_shipped & h_shipped files for the current .l & .y files.

Given a specification of bitfields defined e.g. as follows:
specfile:
{
"field1" : 8,
"field2" : 4,
"field3" : 4
}
and a set of values for setting defaults:
setterfile:
{
"field1" = 0xff,
"field2" = 0xf,
"field3" = 0xf
}
You can generate a binary packed blob as follows:
./blobtool specfile setterfile binaryoutput
binaryoutput: ff ff
The reverse is also possible, i.e. you can regenerate the setter:
./blobtool -d specfile binaryoutput setterorig
setterorig:
# AUTOGENERATED SETTER BY BLOBTOOL
{
"field1" = 0xff,
"field2" = 0xf,
"field3" = 0xf
}
This tool comes with spec/set files for X200 flash descriptor
and ICH9M GbE region, and can be extended or used to decompile
other data blobs with known specs.
