The ZLIB_CONST macro may be used since 1.2.5.2 (17 Dec 2011) to specify that the input buffers are const. This is sufficiently old to cover all non-EOL distributions, i.e. everything we test on.
Compiling on older distributions may generate warnings but will continue to work.

The libbacktrace feature has not been working since the move to meson because libbacktrace detection was not added to the meson build. Add libbacktrace to meson and improve the feature so that it can be compiled into release builds.
The prior implementation fetched line numbers with each stack trace push. Not only was this slow but it missed any functions that were not being tracked on our stack.
Instead just examine the backtrace when an error happens and merge it with the info we have on our stack. If the backtrace is not available then the output remains as before.
Also remove --backtrace from test.pl since the library is now auto-detected.
Leave this library out of the production build for now to give it a little time to shake out in testing.
This is immediately useful because it will detect any extern'd functions or variables that are not being used. It also detects functions or variables that are declared but not defined.
If a FV/VR_EXTERN macro is missing it will be detected either because of a mismatch in the declaration/definition or because a new defined symbol will appear in the nm test.
Eventually the unity build will be used to create a more optimized pgbackrest binary but that will need to wait.

v0.45 ships with Ubuntu 18.04, which is currently the oldest distro we support. We may never do a Meson release on Ubuntu 18.04 but this allows us to start running unit tests with Meson in the meantime.
Some more granular options are not available so we use buildtype in more places.
The check for a in-tree autoconf/make build had to be removed since the filesystem APIs are not available.
Finally, alias_target was removed. This means that full paths must be used for build targets, which does not seem too bad. For instance, test/src/test-pgbackrest must now be used as a build target instead of simple test-pgbackrest.
This provides reproducible builds and minimizes the file path in debug messages, just like an in-tree make build.
For test source, prefix with test/ in case there are any module name collisions.
Having the test harness in C will allow us to remove duplicated Perl code and test on systems where Perl support is not present.
Custom harnesses and shims are currently not implemented, which means only the following tests in the common module will run: error, stack-trace, type-convert, assert-on, mem-context, time, encode, type-object, type-string, type-list, type-buffer, type-variant, reg-exp, log.
The experimental test harness is being committed with partial functionality so it can be used in Windows development. The remaining features will follow as needed.
The meson builds are still experimental so for now the configure/make build process is preferred for release builds. This message should help prevent any automated build systems from picking up meson instead.
Change all instances of __attribute__((__noreturn__)) to a macro in meson.build / build.auto.h.in.
As compiler attributes written in the form of __attribute__ are not supported by MSVC, this is one of several commits to make the code-base more robust and allow using MSVC-style attributes later.
Meson is a new build system that offers simpler syntax and superior performance to autoconf/make. In addition, Windows is supported natively.
The Meson build appears complete, but currently is used only for auto-generation of code and the host build of pgbackrest. Some container upgrades will be required before Meson can be used for container builds.
Also patch the Debian package to force autoconf/make rather than Meson.
