aes: make Td[0-5] and Te[0-5] tables non static

Remove static attribute to Td[0-5] and Te[0-5] tables so that they
can be used outside of aes.c. Change their type from u32 to uint32_t,
to keep the u32 udef local to aes.c. Prefix them with AES_ so that they...

Allow clock_gettime() monotonic clock to be utilized on more OS's

Allow the clock_gettime() code using monotonic clock to be utilized on
more POSIX compliannt OS's. This started as a fix for OpenBSD which was
listed in one function as part of the previous hard coded list of OS's...

oslib-posix: rename socket_set_nonblock() to qemu_set_nonblock()

The fcntl(fd, F_SETFL, O_NONBLOCK) flag is not specific to sockets.
Rename to qemu_set_nonblock() just like qemu_set_cloexec().

qemu-socket: set passed fd non-blocking in socket_connect()

socket_connect() sets non-blocking on TCP or UNIX domain sockets if a
callback function is passed. Do the same for file descriptor passing,
otherwise we could unexpectedly be using a blocking file descriptor....

bitops: unroll while loop in find_next_bit()

this patch adopts the loop unrolling idea of bitmap_is_zero() to
speed up the skipping of large areas with zeros in find_next_bit().

this routine is extensively used to find dirty pages in
live migration.

testing only the find_next_bit performance on a zeroed bitfield...
