09d0dfc481 Document the intention behind mps_ld_isstale rather than the implementation: it captures the intention of testing whether a particular dependency is stale (even though the implementation in fact tests whether any dependency is stale). add new function mps_ls_isstale_any for expressing the intention of testing whether any dependencey is stale. the two functions have the same implementation at present, but the separation gives us the freedom to return a more precise result from mps_ld_isstale in future.

ac1e57c0ac Merging branch/2013-05-17/emergency with major rework of mvt, mvff, and cbs. 
Some parts of this are still ragged, and would not normally pass review, but this is a massive improvement to the existing code.

fa63d63b23 New public function mps_fmt_create_k creates an object format using the keyword argument interface. 
Deprecate the format variant structures (mps_fmt_A_s, mps_fmt_B_s, mps_fmt_auto_header_s, mps_fmt_fixed_s) and the old interface (mps_fmt_create_A, mps_fmt_create_B, mps_fmt_create_auto_header, mps_fmt_create_fixed).

61743c36b4 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).

a7c70df226 Ensure the emergency branch compiles and runs on lii6gc: 
No need for <string.h> in mpsi.c (this defines a function "index" on Linux).
Need more headers in range.c so that it will compile on its own.
Need UNUSED() declarations for some variables in cbstest.c.
