b764d4b19d Improve organization of comm.gmk: 
* Mention each target once (this makes it more reliable to modify the set of targets).
* Include exposet0, expt825 and xmess in the automatically run test cases.
* For other test cases, explain why not included in automated test suite.
* Organize targets alphabetically (this is makes it easier to check the lists against each other).

0260380dd3 Rename cbstest.c to fbmtest.c (free block management test) and generalize it so that it tests both the cbs and freelist modules. 
Split FreelistFind into FreelistFindFirst and FreelistFindLast so that the interface exactly matches the CBS interface.
Fix errors in freelist.c: missing computation of size in FreelistBlockSetLimit; update linked list correct in coalesceRight case in FreelistInsert.
Avoid compiler warnings in freelist.c.
In cbs.c: use $U for Booleans ($B is for bit tables).

db9328da7a Use range objects in the cbs interface instead of base, limit pairs. the idea is that freelist and cbs should offer similar interfaces so that the testing code can be shared.

Since ABQDisposition enumeration only has two values, it's better to use Bool.

* Remove unused function mps_mvff_stat.
* Don't call range methods in RangeCheck.
* RangeInit can't fail, so return void.

3c48eff730 On platform lii6gc, the mps needs a bunch of symbols which are not defined if the -ansi option is given to gcc. these can be enabled by defining features like _gnu_source, but all headers share a common set of features (via <feature.h>) and so all sources in the same compilation unit must turn on the same set of features. make sure this happens by turning on the features in config.h (not mpstd.h). 
Remove <string.h> from mpsi.h (not needed).

No need for <string.h> in mpsi.c (this defines a function "index" on Linux).
