the partially buggy implementations found accross fstools and procd.

Some gcc versions have issues with the __builtin_choose_expr construct
which attempts to automatically use the const versions of those
functions.
Make it possible to explicitly use const_* versions to avoid that.

g++ does not support __builtin_choose_expr, so we can't support
byte swapping as constant expression there.

Simplifies portability and ensures that cpu_to_* can be used in const
declarations. If the architecture has special instructions, the compiler
should be able to detect the pattern and use them.

The bitfield functions and macros were committed without explaining
their purpose in the commit message.
As they are only used in uci, and conflict with similar functions added
in hostapd, breaking our hostapd ubus patch, nuke them from libubox and
add them in uci instead.
If we need them anywhere else in the future we can add it to libubox
again, but preferably prefixed with ubox_.

This creates a mapping with twice the size of the allocated memory. The
second half of that mapping points at the same memory as the first half.
This is useful for ring buffers, because any read starting in the first
half can overflow into the second half as long as the read size is
smaller than the size of the memory area.

It turns out that mach_absolute_time() is not monotonic at all. While
at it, convert the CLOCK_REALTIME implementation to using
clock_get_time() as well.
