Most libraries use the "-host" suffix when building for the host. This
patch renames all the libraries to use -host instead of _host.

While the main blkid functionality is in util-linux, there is still
use for blkid on non-Linux platforms.
Fix the ZFS device detection by looking at multiple uberblocks to
see if any are present, rather than looking for the ZFS boot block
which is not always present.
There are slots for up to 128 uberblocks, but the first 4 are not
written to disk on a newly-formatted filesystem, so check several
of them at different offsets within the uberblock array.

Add missing new lib/ext2fs source files that were added for encryption
support. Also move configuration #define's from individual Android.mk
to the android_config.h file, since we've moved away from specifying
configuration #define's on the command-line upstream.

The Android.mk files were taken from the Android AOSP sources, and
updated for the 1.43 next branch. The intention is that this will
allow the repository which is currently located in external/e2fsprogs
with one which is based off of the upstream e2fsprogs. Right now
external/e2fsprogs was not created using "git clone", so it means that
git merges don't work. After the external/e2fsprogs Android
repository is replaced, with one based off the upstream repository,
Android will be able to synchronize with the upstream repository by
pulling and merging from upstream, and then running the script
"./util/gen-android-files" to update any generated files. (This is
necessary because in the Android build system, the Android.mk files
are rather stylized and don't make it easy to run arbitrary shell
scripts during the build phase.)

Commit 3e683eef93 ("define bitwise types and annotate conversion
routines") broke the build on various platforms. Turns out that
crossing our fingers wasn't such a good idea, so just define it
separately.

Most systems have a backwards compatibility symlink in
/usr/include/syscall.h to /usr/include/sys/syscall.h, but

Try to avoid name clashes with definitions of __u8, __u16, __u32,
and __u64 in userspace, in case other headers also define these
types. Define HAVE___{S,U}{8,16,32,64} preprocessor macros to
show that these types are already defined.
This would avoid the need to check for _BLKID_TYPES_H in ext2_types.h
and _EXT2_TYPES_H in blkid_types.h, but since older versions of these
headers did not use HAVE___U8 et.al. keep these checks around for now.
Report an error if there are no 64-bit types available. The code
will not compile if these are not available.

The LIST_HEAD macro is not directly used in getsize.c, so
<sys/queue.h> is not needed at all, and could cause confusion at
some later point if the Linux-style list macros are ever used.
Build was verified on MacOS which defined HAVE_SYS_DISK_H true.
I manually inspected the sources for recent *BSD headers to check
if this was needed there or not. MacOS and FreeBSD <sys/disk.h>
do not use lists at all. NetBSD and OpenBSD <sys/disk.h> and all
of the <sys/mount.h> headers include <sys/queue.h> internally.
I used http://fxr.watson.org/fxr/source/sys/mount.h?v={OSTYPE}
as a reference, checking both old and new *BSD versions.

The "mkswap" program is not available on MacOS, so just use the
existing swap0.img.bz2 and swap1.img.bz2 files directly.
Because MacOS HFS+ doesn't support sparse files (welcome to the 80's)
the m_bigjournal test takes forever to zero out the whole 42GB test
filesystem. Skip this test for Darwin kernels for now.
Unfortunately, neither "df -T" nor "stat -f -c %T" is available on
MacOS to directly determine the filesystem type, and I'm too lazy
to parse the output of "mount" and match it to the path of the test
directory in shell, so it just checks the kernel type and assumes
the filesystem type is HFS and skips the test.
Since this test runs on Linux the majority of the time, the loss of
test coverage is minimal. If MacOS should ever get a real filesystem,
this can be revisited.

Compiling with LLVM generates a large number of warnings due
to the use of _() for wrapping strings for i18n:
warning: format string is not a string literal
(potentially insecure) [-Wformat-security]
./nls-enable.h:4:14: note: expanded from macro '_'
#define _(a) (gettext (a))
^~~~~~~~~~~~
These warnings are fixed by using "%s" as the format string,
and then _() is used as the string argument.

Don't print a verbose configure error in parse-types.h if
<asm/types.h> missing and __[SU]*_TYPEDEF is unset. This is
always the case for non-Linux builds.
The printf formatting strings all use "%llu" for printing 64-bit
values and this it produces a large number of warnings if __u64
is defined as "unsigned long". If __U64_TYPEDEF isn't set use
"unsigned long long" for __u64 in ext2-types.h and blkid-types.h
by default instead of using "unsigned long".
Fix a few places where "%d" or "%u" or "%Lu" were used to print a
64-bit value, by converting them to use "%lld" or "%llu" instead.
Fix a few places where "%lu" was used to print .tv_usec, by casting
the variable to "(long)" since .tv_usec is "int" on some systems.

Run sparse against source files when building e2fsprogs with 'make C=1'. If
instead C=2, it configures basic ext2 types for bitwise checking with sparse,
which can help find the (many many) spots where conversion errors are
