6fcaf83c98 Cleanup MOCK_IMPL (etc) to be findable with etags

even our special AM_ETAGSFLAGS couldn't find them.

d950ad0dfd Remove call to get_unquoted_path in config_process_include() 
parse_config_line_from_str_verbose() already looks for strings
that are surrounded by quotes, and processes them with
unescape_string().  So things were getting decoded twice, which was
(in turn) playing havoc with backslashes on Windows.

c486ef57a3 Rename x-lzma to x-tor-lzma

531835f561 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.

Enforce 16 MB upper bound of memory usage in LZMA decoder. 
This patch changes two things in our LZMA compression backend:

- We lower the preset values for all `compression_level_t` values to
  ensure that we can run the LZMA decoder with less than 65 MB of memory
  available. This seems to have a small impact on the real world usage
  and fits well with our needs.

- We set the upper bound of memory usage for the LZMA decoder to 16 MB.

Only compare the first 3 bytes when trying to detect LZMA compression. 
This patch changes the logic in `detect_compression_method()` to only
