efidp_size will return the size, in bytes, of a EFI device path
structure. This is a convenience wrapper in the same style as the
other linux routines. It's implemented by GetDevicePathSize from EDK2
we already needed for other things.

Move tables that were previously in truss over to libsysdecode. truss
output is unchanged, but kdump has been updated to decode these fields.
In addition, sysdecode_sysarch_number() should support all platforms

o Add File to the mUefiDevicePathLibDevPathFromTextTable table so we
don't include 'File()' in the supposed path name. This happens because
of a possible misfeature in the EDK2 code where any path that's not
recognized is treated as a File() node.
o Convert utf8 input into ucs2 output rather than just copying the
utf8 and hoping for the best (no good comes from that).
o Remove bogus comment about needing to add 1. The dummy array already
is length 1, so that's included in sizeof the struct, so there's no
need to add it.

Device paths encoded into the FILEPATH_DEVICE_PATH are UCS2 not
ASCII/UTF8. Convert to utf8 and print that when printing File
paths. Also, since File may be at the end of a long device path,
output File() around the path so it doesn't just show up as random
nodes that might accidentally match real node paths names and cause
errors.
LLVM's MIPS assembler parser does not understand the GNU as
'.gnu_attribute' keyword. This could be re-enabled if LLVM is updated
in the future. The desired floating point ABI is already described in
the .MIPS.abiflags section.

LDBL_MAX is broken on i386:
https://lists.freebsd.org/pipermail/freebsd-numerics/2012-September/000288.html
Gcc has produced +Infinity for LDBL_MAX on i386 and amd64 with -m32
for some time, and newer versions of gcc are now warning that the
"floating constant exceeds range of 'long double'". Avoid this by
referring to proxy values instead.

conversion functions use SSE2 instructions, but these are not guarded by
#ifdef __SSE2__, and there is no implementation using general purpose
registers. For these functions, use the generic C variants instead,
otherwise they will cause SIGILL on older processors.

getmntinfo(3) is designed around a relatively static or slow growing set of
current mounts. It tried to detect a race with somewhat concurrent mount
and re-call getfsstat(2) in that case, looping indefinitely. It also
allocated space for a single extra mount as slop.
In the case where the user has a large number of mounts and is adding them
at a rapid pace, it fell over.
This patch makes two functional changes:
1. Allocate even more slop. Double whatever the last getfsstat(2) returned.
2. Abort and return some known results after looping a few times
(arbitrarily, 3). If the list is constantly changing, we can't guarantee
we return a full result to the user at any point anyways.
While here, add very basic functional tests for getmntinfo(3) to the libc
suite.

Note that I have not been able to trigger this bug with fetch(1), nor
do I believe it is possible, as libfetch always parses the host:port
