resource.c: Don't manually align buffer for uncompressed data
The main reason this was being done was to speed up LZX postprocessing,
but that now can use the vectorized version (with a tiny bit of overhead)
even if the start of the buffer is not 16-byte aligned.

LZX pre/post-processing improvements
- much faster inner loop for non-vectorized version
- use either SSE2 or AVX-2 for vectorized version
- faster inner loop for vectorized version
- support vectorized version on buffers that are not properly aligned

Don't run man pages through configure
The only remaining reason is to update the version number, but there is
already a sed command being run to update all the dates. So we might as
well simplify by just having the unmodified man pages.

Remove support for --with-imagex-progname configure option
The program is always called "wimlib-imagex" now. I expect no one is
using the configuration option, and nothing stops the user from renaming
the binary anyway.

Remove support for --enable-more-assertions configure option
The only uses of wimlib_assert2() were in compression code (where
problems are relatively easy to detect), and this option was disabled by
default anyway. Simplify by just having one kind of assertion.

tagged_items.c: length should be rounded up when adding item
Also 0-fill the new item, including the padding.
These changes have no effect on the only caller of
inode_add_tagged_item() but should be made for correctness in case this
function gets more callers in the future.

new internal image deletion helper
Define a new helper function delete_wim_image() and use in
wimlib_delete_image() and in the error path of
wimlib_add_image_multisource().
This fixes a bug: current_image wasn't being reset to WIMLIB_NO_IMAGE in
the error path of wimlib_add_image_multisource(). Bad things would
happen if the library user then continued to use the same WIMStruct.

portability and compression cleanups
- Split compiler.h into compiler.h and compiler-gcc.h
- Compile with -std=c99. Some GCC extensions are still used but they are
explicitly defined in compiler-gcc.h.
- Add get_unaligned_uXX_le() and put_unaligned_uXX_le() helpers
- Faster lz_copy() in some cases
- Faster lz_extend() in some cases
- New bitops.h header

wimlib_export_image(): cleanups and fixes for rollback
- rollback setting of wimboot flag correctly (actually, don't even set it
until we've succeeded)
- on rollback, free wim_lookup_table_entries in the destination if and
only if they were exported. Before it was possible for one to be freed
if it happened to have had 0 reference count before.

Fix for rewriting uncompressed resources when exporting from solid WIM
The changes from commit 1ba2a3422b ("Workaround for WOF incompatibility")
are resulting in excessive, expensive decompressions when exporting small
incompressible files from solid blocks. For now, add an optimization for
single chunk resources which prevents this common case from triggering
the degenerate behavior.

Remove "memory exhausted" error messages
Calling code checks for NULL returns anyway, and in the case of
allocating chunk compressors there is a fallback so there shouldn't
be an error message.
