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.
