* Move core library sources into src/lib/core
* Move command-line programs into src/cli

* To be more aligned with conda_provides, the version spec has been consolidated into one argument

* This results in a fully activated environment; shell functions and all

* Add python_package_exists() function

* Poll pypi.org or compatible index to see if a package exists
* Returns non-zero on success

* Implements python_package_exists() in delivery_defer_packages()

* Implements python_package_exists() in delivery_defer_packages()

* Bugfix: Avoid incorrect package selection

* With large package lists that contain multiple packages starting with the same strstr() would pick the first match
* This adds a temporary name variable that strcmp() can check against.

* Message correction:

* Change "release" to "testing" in testing environment failure message

* Amend message to fit the flow of the output

* Disable outdated conda notifications

* The latest version isn't always the greatest. Don't give the end-user any ideas. Just use whatever the installer provides... quietly

* Rename python_package_exists to pip_index_provides

* Document the function prototype
* Add missing comments in micromamba structure

* Ensure the temporary output file does not linger

* The array of packages now used to check the runtime environment instead of two separate scanning methods
* Renamed tools array to: conda_minimum_viable_tools

* Change return value of conda_setup_headless() from void to int

* Replace exit() with return;

* Return early if unpacking the micromamba binary fails

* Exit program when pointer to INIFILE is NULL.

* Validation function cannot otherwise proceed

* The way the logic is set up I've decided to duplicate the installation code for now until I find time to revise it

* The only meaningful difference between a "fresh start" and reusing the conda installation is a rmtree().

* Exposes STASIS_DOWNLOAD_TIMEOUT environment variable

* Sets the connection timeout for libcurl to 30, instead of 300.

* Export ini_section_create() function

* Add download() tests

* Add conda_*() tests

* Add boilerplate source file for test framework

* Fixes segfault reported by @GeorgeJCleary (#10)

* The key is now an array index. When key is -1, the env variable is not defined.

* Free resources only when continue on error is disabled (#11)

* Fix segfault due to premature shutdown/cleanup

* If conda_setup_headless cannot succeed, die

* Set STASIS_SYSCONFDIR for tests

* Add github.c and github.h

* Implements get_github_release_notes()

* Remove unused variables

* Fix circular dependency on tplfunc_frame

* Remove predeclaration of tplfunc_frame
* tpl_register_func accepts pointer to void instead
* tpl_register_func sets maximum number of arguments
* Frame is generated within tpl_register_func

* Improve template function error handling and return/output management

* Remove redundant extern statement

* Include github.h and template_func_proto.h in core.h

* Expose get_github_release_notes_tplfunc_entrypoint function to template engine

* Add template_func_proto.c and template_func_proto.h

* Replace free() with guard variant

* Fix test_template::test_tpl_register_func

* Fix tests

* Fix tests

* cmd should be at least PATH_MAX in size.

* Magic number caused failure to install conda with a long installation path

* Implement get_github_release_notes_auto function that bases release note data off test contexts

* Disable overwriting releases by default

* Add automatic release note generation function call to release_notes.md.in

* Fix test_tpl_register_func()

* Add enough space for tar command plus a path

* Fix circular include

* Github functions do not require access to core.h anyway

* Add comments to union

* Update README to mention template function availability

* Add EnvCtl structure
* Add runtime checks to avoid running all the way to the end only to be met with a configuration error.
* Rename GITHUB to GH

* Development docs pre-rough-draft

* Pass .ci_support/plat_arch_.yaml to conda-build

* Fixes a few outstanding leaks in delivery context

* Move micromamba function out of stasis_indexer.c

* Adjust code in the indexer to accommodate the move. The function now expects a MicromambaInfo structure as its first argument.

* Add missing warning message

* User is informed when pandoc is not available for HTML page generation

* Initialize workdir_template string to zero

* Add micromamba program to runtime PATH

* Expose storage.tools_dir to template engine

* Remove dead code

* Fix wording in comment

* Fix conda-forge builds

* Pass their .ci_support configurations to conda-build in order to fully set up their build runtime environment

* Add get_cpu_count()

* Exposes STASIS_CPU_COUNT and CPU_COUNT to the runtime environment

* Implements conda reactivation template string

* {{ workaround.conda_reactivate }}
* This is useful to call after installing any conda packages within a test.script

* Fix conda runtime inside of test.script

* This ensures conda and mamba are fully initialized.
* Previous behavior only placed the commands on the PATH but didn't provide any shell macros (i.e. undefined behavior)

* Document CPU_COUNT and workaround.conda_reactivate
