mips: extend mips_features with a check for FPU

Extend mips_features with "hard-float" query to which mips_features will
respond whether or not the platform is meant to have a floating point unit.
The query is not a runtime check, but a built-time check.

mips64: run FPU tests only when FPU is available

Check whether the target platform is meant to have an FPU before executing
tests that make use of a floating-point unit.

mips64: enable soft-float build of the tests

Cavium toolchain defaults to soft-float, so it is important to enable full
build of the test suite to work in that case as well.

This boils down to protecting FPU-specific code segments with

#if defined(__mips_hard_float)
#endif

Remove unneeded header file which does not exist on Darwin.
Disable test for darwin as pthread_setname_np is not implemented.
But setting and observing the threadname is what this test is all about.

Merge revisions 14203,14574,14575 from the BUF_REMOVAL
branch to trunk.
This change eliminates the fixed size buffers in VG_(basename)
and VG_(dirname).

Merge 14206,14207,14261,14577,14578 from BUF_REMOVAL branch to trunk.
This changes VG_(record_startup_wd) to dynamically allocate a large
enough buffer for the directory name. As the dynamic memory manager has
started up a while ago, this is quite safe. Also rewrite VG_(get_startup_wd)
to simply return the directory name. No more messing with copying it
around. Adapt call sites.

Merge r14208 from BUF_REMOVAL branch to trunk.
In function read_dot_valgrindrc use a large enough buffer 
allocated on the stack. 
Also assert that the passed in directory is not NULL. This is 
true at all call sites. The old code would have attempted to read
/.valgrindrc for dir == NULL and I don't think we want that.

Merge r14209 from BUF_REMOVAL branch to trunk.
In VG_(redir_notify_new_DebugInfo) use a large enough buffer
allocated on the stack.
