* Added C99 functions floorf, ceilf, [l]rint[f], trunc[f], [l]round[f], nearbyint[f] and remainder[f].

* Added macros (only) for sinf, cosf, atanf.
* Requires cc 5.43

This involves adding 36 new entries to the stubs. Current versions of the C
library will not fault client programs with such larger stubs, but will fill
in the extra entries with junk. Programs requiring the new functions will have
to RMEnsure this version of the Shared C Library.

This version of the C library has been fixed so that in future, any extra
unknown stubs entries will be filled in with a branch to zero, rather than
corrupted.

Requires cc 5.41 or later, both to build, and to make use of some of the extra
facilities.
