This completes our tar utility by implementing the -c option
for archive creation using TarOutputStream and optionally
GzipCompressor for compression via the -z option.
Since we ignore both the ustar prefix field and the gnu extended
header right now anyways, we can just accept both formats as the
rest of the header is exactly the same.
This commit implements a stream compressor for the gzip
specification (RFC 1952), which is essentially a thin
wrapper around the DEFLATE compression format.
This commit adds a fully functional DEFLATE compression
implementation that can be used to implement compression
for higher level formats like gzip, zlib or zip.
A large part of this commit is based on Hans Wennborg's
great article about the DEFLATE and zip specifications:

After we moved to storing the text of each token in the token itself,
we no longer have to store the source of the program in the Parser.
This makes more sense because the parser should deal with tokens, not
with raw source code.
Tests: Improve munmap-test
We now Unmap page aligned and check if the regions were really unmappped etc.
Tests: Cleanup Munmap-test
added a cleanup and removed a useless cast
This implements a fallback to munmap that unmaps multiple regions at a
time, with splitting some when needed.
The way it is implemented is possibly not optimal, due to it searching
without looking into the cache
Instead of blindly resetting every AHCI port, let's just reset only the
controller by default. The user can still request to reset everything
with a new kernel boot argument called ahci_reset_mode which is set
by default to "controller", so the code will only invoke an HBA reset.
This kernel boot argument can be set to 3 different values:
1. "controller" - reset the HBA and skip resetting AHCI ports
2. "none" - don't reset anything, so we rely on the firmware to
initialize the AHCI HBA and ports for us.
3. "complete" - reset the AHCI HBA and ports.
Instead of waiting for the AHCI HBA to reset the signature after SATA
reset sequence, let's just check if the Port x Serial ATA Status
register was set to value 3, indicating that device was detected
and phy communication was established.
The intention is to make the boot to be faster, therefore we should
decrease the time deltas in timeout loops to allow earlier break
from these.
Also, there's no need to wait 10 milliseconds before setting
the interface state to "no action request" during the reset sequence.
Running the tests will be moved to a separate test command which can
then leverage the availability of different targets and run either unit
tests on the host or the image in QEMU in self-test mode. :^)
- Only call ensure_toolchain for non-lagom targets
- Use host addr2line, we can't expect the i686 toolchain's addr2line to
support the host's binary executable format
- Don't export SERENITY_ARCH and TOOLCHAIN_DIR, don't need them anymore
