Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use
it to get real uninitialized memory on no-mmu systems. This avoids a lot
of normally useless overhead involved in zeroing out all of the memory
(sometimes multiple times).

Most ports have the same exact mman bit defines, so let's unify things
like the linux kernel has with the asm-generic efforts.
A few ports are left behind as they are non-trivial to merge -- the arch
maintainers can tackle it if they care.

Also, remove unneeded __need_timespec (It cuts off a tiny bit of
work for CPP but is of course not strictly needed).

This optimization is based on prefetching and 64bit data transfer via FPU
(only for the little endianess)
Tests shows that:
----------------------------------------
Memory bandwidth | Gain
| sh4-300 | sh4-200
----------------------------------------
512 bytes to 16KiB | ~20% | ~25%
from 32KiB to 16MiB | ~190% | ~5%

We don't provide spawn.h let alone any other spawn funcs/types, so don't
set up the _POSIX_SPAWN define that some packages (like vlc) check.

Assign each field one by one rather than stack initialization as gcc will
call memset() to zero out the rest of the structure -- which we don't care
about as the field is unused and not seen outside of the libc.

sem_open(3) needs to create a temporary file in a way which can't
be efficiently implemented in terms of POSIX API. Extend
__gen_tempname with mode_t mode argument in order to ease
sem_open implementation.

The malloc() code checks the incoming size to make sure the header
adjustment doesn't cause overflow in the size storage. Add the same
check to realloc() to catch stupid stuff like realloc(..., -1).

We don't really need to know the exact symbol that caused a failure as
long as we know where to start looking. So unify the duplicate code
between all funcs and between the sparc variants. This gives us a nice
code shrink of ~95%.
