Instead of using a ReST compilant label while parsing,
move the label to ReST output. That makes the parsing logic
more generic, allowing it to provide other types of output.
As a side effect, now all files used to generate the output
will be output. We can later add command line arguments to
filter.

The usage of literal blocks make the document very complex,
causing the browser to take a long time to load.
On most ABI descriptions, they're a plain text, and don't
require a literal block.
So, add a logic there with identifies when a literal block
is needed.
As, on literal blocks, we need to respect the original
document space, the most complex part of this patch is
to preserve the original spacing where needed.

This patch adds the test cases for checking compressed firmware load.
Two more cases are added to fw_filesystem.sh:
- Both a plain file and an xz file are present, and load the former
- Only an xz file is present, and load without '.xz' suffix
The tests are enabled only when CONFIG_FW_LOADER_COMPRESS is enabled
and xz program is installed.

This patch adds the support for loading compressed firmware files.
The primary motivation is to reduce the storage size; e.g. currently
the files in /lib/firmware on my machine counts up to 419MB, while
they can be reduced to 130MB by file compression.
The patch introduces a new kconfig option CONFIG_FW_LOADER_COMPRESS.
Even with this option set, the firmware loader still tries to load the
original firmware file as-is at first, but then falls back to the file
with ".xz" extension when it's not found, and the decompressed file
content is returned to the caller of request_firmware(). So, no
change is needed for the rest.
Currently only XZ format is supported. A caveat is that the kernel XZ
helper code supports only CRC32 (or none) integrity check type, so
you'll have to compress the files via xz -C crc32 option.
Since we can't determine the expanded size immediately from an XZ
file, the patch re-uses the paged buffer that was used for the
user-mode fallback; it puts the decompressed content page, which are
vmapped at the end. The paged buffer code is conditionally built with
a new Kconfig that is selected automatically.

The firmware loader queries if LSM/IMA permits it to load firmware
via the sysfs fallback. Unfortunately, the code does the opposite:
it expressly permits sysfs fw loading if security_kernel_load_data(
LOADING_FIRMWARE) returns -EACCES. This happens because a
zero-on-success return value is cast to a bool that's true on success.
Fix the return value handling so we get the correct behaviour.
