This patch refactors our streaming compression code to allow us to
extend it with non-zlib/non-gzip based compression schemas.
See https://bugs.torproject.org/21663
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.

The consdiff generation logic would skip over lines added at the start of the
second file, and generate a diff that it would the immediately refuse because
it couldn't be used to reproduce the second file from the first. Fixes#21996.
The reason for making the temporary list public is to keep it encapsulated in
the rendservice subsystem so the prop224 code does not have direct access to
it and can only affect it through the rendservice pruning function.
It also has been modified to not take list as arguments but rather use the
global lists (main and temporary ones) because prop224 code will call it to
actually prune the rendservice's lists. The function does the needed rotation
of pointers between those lists and then prune if needed.
In order to make the unit test work and not completely horrible, there is a
"impl_" version of the function that doesn't free memory, it simply moves
pointers around. It is directly used in the unit test and two setter functions
for those lists' pointer have been added only for unit test.

Now we have separate getters and setters for service-side and relay-side. I
took this approach over adding arguments to the already existing methods to
have more explicit type-checking, and also because some functions would grow
too large and dirty.
This commit also fixes every callsite to use the new function names which
modifies the legacy HS (v2) and the prop224 (v3) code.

One of the goals of this change is to have trunnel API/ABI being more explicit
so we namespace them with "trn_*". Furthermore, we can now create
hs_cells.[ch] without having to confuse it with trunnel which used to be
"hs_cell_*" before that change.
Here are the perl line that were used for this rename:
perl -i -pe 's/cell_extension/trn_cell_extension/g;' src/*/*.[ch]
perl -i -pe 's/cell_extension/trn_cell_extension/g;' src/trunnel/hs/*.trunnel
perl -i -pe 's/hs_cell_/trn_cell_/g;' src/*/*.[ch]
perl -i -pe 's/hs_cell_/trn_cell_/g;' src/trunnel/hs/*.trunnel
And then "./scripts/codegen/run_trunnel.sh" with trunnel commit id
613fb1b98e58504e2b84ef56b1602b6380629043.
Fixes#21919

These tests tried to use ridiculously large buffer sizes to check
the sanity-checking in the code; but since the sanity-checking
changed, these need to change too.
Test base64_decode() with odd sized decoded lengths, including
unpadded encodings and padded encodings with "right-sized" output
buffers. Convert calls to base64_decode_nopad() to base64_decode()
because base64_decode_nopad() is redundant.
Check that route_len_for_purpose() (helper for new_route_len())
correctly fails a non-fatal bug assertion if it encounters an
unhandled circuit purpose when it is called with exit node info.
