lix, where modularity is made up and the patterns don't matter. merging
everything to match actual behavior of the system makes using rust much
easier because we'll have only *one* library to link, not half a dozen.
Change-Id: Ie3cb1db659798511128716402497697320bd0484
Adds an example plugin implementing an mTLS-enabled binary cache store
(https+mtls:// scheme) using client certificates for authentication.
Darwin fix: don't link liblix* into plugins (host resolves symbols at
runtime via dynamic_lookup). Explicitly link curl so it binds to
Nix-store libcurl, not /usr/lib/libcurl. This prevents the plugin's
curl_easy_setopt calls from operating on the wrong libcurl instance.
Test portability: BSD sed -i wrapper, OpenSSL -sha256 for cert signing,
redirect test server output to log file.

This is a collection of Lix plugins that showcase how to write one for
various usecases.
The first is a mTLS store plugin that enable mTLS cache URIs
(`https+mtls://`).
We enable meson build system support for this plugin but we are not
going to distribute it in the official packaging of Lix, we will
repackage each relevant plugin downstream in Nixpkgs.
These plugins have *NO* guarantee support, they are provided as useful
references and are possibly production-ready if your usecase is simple
enough.
Reference: https://github.com/NixOS/nix/pull/13030 (this change has
resemblances but our APIs are different, the tests harness is mostly
from CppNix).

if direction == "entered":

elif direction == "exited":
dur = time - timestack.pop()

Includes test cases around function call failures and tryEval. Uses
RAII so the finish is always called at the end of the function.
