Move elog_internal.h to commonlib/bsd/include

Browse Source 
Move elog_internal.h to commonlib/bsd/include/bsd/.
And rename it from elog_internal.h to elog.h.

Since this file will be included from util/ it also converts the "uNN"
types into "uintNN_t" types.

The two defines that are not used by util/ are moved to
drivers/elog/elog.c, the only file that includes them.

Move also the function elog_verify_header() from drivers/elog/, to
commonlib/bsd/elog.c since this function will be called from util/
as well.

The rationale behind moving elog's defines & structs to
commonlib/bsd/include is to make them available to util/ tools and/or
payloads (should it be needed in the future).

The files that are being relicensed to BSD were coded by Duncan Laurie,
and he is Ok with the relicense.
