[MIPS]: Use mcontext_t structure for MIPS

Browse source 
This change removes user_regs_struct and
user_fpregs_struct structures for mips
and uses mcontext_t instead.

// The purpose of this file is to glue the mismatching headers (Android NDK vs
// glibc) and therefore avoid doing otherwise awkward #ifdefs in the code.
// The following quirks are currently handled by this file:
// - MIPS: Keep using forked definitions of user.h structs. The definition in
// the NDK is completely different. Internal bug b/18097715
// - i386: Use the Android NDK but alias user_fxsr_struct > user_fpxregs_struct.
// - x86_64: Override a typo in user_fpregs_struct (mxcsr_mask -> mxcr_mask).
// The typo has been fixed in NDK r10d, but a preprocessor workaround is
// required to make breakpad build with r10c and lower (more details below).
// - Other platforms: Just use the Android NDK unchanged.
