Since we have a streaming API for each compression backend, we don't
need a non-streaming API for each: we can build a common
non-streaming API at the front-end.
This commit adds the src/trace directory containing the basics for our tracing
subsystem. It is not used in the code base. The "src/trace/debug.h" file
contains an example on how we can map our tor trace events to log_debug().
The tracing subsystem can only be enabled by tracing framework at compile
time. This commit introduces the "--enable-tracing-debug" option that will
make all "tor_trace()" function be maped to "log_debug()".

This patch adds support for checking if a given `compress_method_t` is
supported by the currently running Tor instance using
`tor_compress_supports_method()`.

This patch adds support for enabling support for Zstandard to our configure
script. By default, the --enable-zstd option is set to "auto" which means if
libzstd is available we'll build Tor with Zstandard support.

This patch adds support for enabling support for LZMA to our configure
script. By default, the --enable-lzma option is set to "auto" which
means if liblzma is available we'll build Tor with LZMA support.

The item referred to the cdm_ht_set_status() case where the item was
not already in the hashtable. But that already happens naturally
when we scan the directory on startup... and we already have a test
for that.
This commit adds some helper functions to look up the diff from one
consensus and to make sure that applying it leads to another. Then
we add them throughout the existing test cases. Doing this turned
up a reference-leaking bug in consensus_diff_worker_replyfn.
Initial tests. These just try adding a few consensuses, looking
them up, and making sure that consensus diffs are generated in a
more or less reasonable-looking way. It's enough for 87% coverage,
but it leaves out a lot of functionality.
This patch refactors our streaming compression code to allow us to
extend it with non-zlib/non-gzip based compression schemas.

To allow us to use the API name `tor_compress` and `tor_uncompress` as
the main entry-point for all compression/uncompression and not just gzip
and zlib.

This patch changes some of the tt_assert() usage in test_util_gzip() to
use tt_int_op() to get better error messages upon failure.
Additionally we move to use explicit NULL checks.
