If one uses -L $PATH to point to a full chroot, the startup time
is significant. In addition, the existing probing algorithm fails
to handle symlink loops.
Instead, probe individual paths on demand. Cache both positive
and negative results within $PATH, so that any one filename is
probed only once.
Use glib filename functions for clarity.

Move declarations out of qemu-common.h for functions declared in
utils/ files: e.g. include/qemu/path.h for utils/path.c.
Move inline functions out of qemu-common.h and into new files (e.g.
include/qemu/bcd.h)

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

In this file, we don't check the return value of malloc/strdup/realloc which may fail.
Instead of using these routines, we use the GLib memory APIs g_malloc/g_strdup/g_realloc.
They will exit on allocation failure, so there is no need to test for failure,
which would be fine for setup.

While dirent->d_type is 8 bit for most systems, it is 32 bit for MinGW.
Reducing it to 8 bit results in a compiler warning because the macro
is_dir_maybe compares that 8 bit value with 32 bit constants.
Using 'unsigned' instead of 'unsigned char' matches the declaration for
MinGW and does not harm the other systems.
MinGW-w64 is not affected: it does not declare d_type.

g_strdup_printf already handles OOM errors, so some error handling in
