Increase MALLOC_MP_LIM to 16MB
...
Increase the maximum allowed size passed to mprotect(PROT_WRITE)
from 1MB to 16MB. This was necessary with the glibc allocator
in order to allow worker threads to allocate more memory --
which in turn is necessary because of our new use of worker
threads for compression.
Closes ticket #22096 . Found while working on #21648 .

Refactor compression tests into a single test.

This patch refactors our compression tests such that deflate, gzip,
lzma, and zstd are all tested using the same code.
Additionally we use run-time checks to see if the given compression
method is supported instead of using HAVE_LZMA and HAVE_ZSTD.

Approximate memory usage needed for the LZMA backend.
...
This patch adds support for measuring the approximated memory usage by
the individual `tor_lzma_compress_state_t` object instances.
The LZMA library provides the functions `lzma_easy_encoder_memusage()`
and `lzma_easy_decoder_memusage()` which is used to find the estimated
usage in bytes.

Store compression overhead from tor_compress_state_t.

The `tor_compress_state_t` data-type is used as a wrapper around the
more specialized state-types used by the various compression backends.
This patch ensures that the overhead of this "thin" wrapper type is
included in the value returned by `tor_compress_get_total_allocation()`.
