deduplicate bits/mman.h currently five targets use the same mman.h constants and the rest share most constants too, so move them to sys/mman.h before the bits/mman.h include where the differences can be corrected by redefinition of the macros. this fixes two minor bugs: POSIX_MADV_DONTNEED was wrong on most targets (it should be the same as MADV_DONTNEED), and sh defined the x86-only MAP_32BIT mmap flag.

#undef MAP_ANON
fix MAP_ANONYMOUS value for mips, remove cruft copied from i386

#undef MAP_NORESERVE
add MAP_NORESERVE to bits/mman.h this is needed for qemu, and since it differs for each arch it can't be circumvented easily by using a macro in CFLAGS.

#undef MAP_SYNC
initial version of mips (o32) port, based on work by Richard Pennington (rdp) basically, this version of the code was obtained by starting with rdp's work from his ellcc source tree, adapting it to musl's build system and coding style, auditing the bits headers for discrepencies with kernel definitions or glibc/LSB ABI or large file issues, fixing up incompatibility with the old binutils from aboriginal linux, and adding some new special cases to deal with the oddities of sigaction and pipe syscall interfaces on mips. at present, minimal test programs work, but some interfaces are broken or missing. threaded programs probably will not link.
