* original pointer is no longer modified
* token strings are stripped of leading space before appending to the list

* ini_getval_* functions now able to affect rendering mode using INI_READ_RAW and INI_READ_RENDER
* Created pointers to deeply nested structures to increase readability
* Output from ini_write() is more consistent, with fewer errant spaces and line feeds
* Fixes accidental regression in #19. INIVAL_TYPE_STR_ARRAY never produced an array of pointers to char. This needs to be corrected in the future. i.e. It has always generated a new-line delimited string, not a StrList, or array.

* Free the function key string in tplfunc_frame during tpl_free()

* Fix leaks in get_github_release_notes_auto_tplfunc_entrypoint():

* Free repository name
* Free list of release notes

* Add handler for space-delimited lists

* This needs attention, however. The INI writer has no way to know a list with spaces is a list; this happens in the value conversion functions.
* Add type_hint member to INIData structure. At some point support with be added for all INIVAL_TYPE_* defines. Right now it's only used with arrays.
* Zero out line buffer in ini_open after each iteration
* Do not strip raw INI data. Let the conversion functions handle it
* Add spaces to key value pairs in rendered INI output.

* Add ini_getvar_TYPE() functions

* These replace the functionality of static conv_TYPE() functions in delivery.c
* Add support for missing types: U/CHAR, U/SHORT, STRLIST

* ini_getval: expand template variables immediately before processing the output

* Strip leading space to avoid issues with string comparisons against the result

* ini_getval: Return copies, not the original.

* This forces one to use ini_setval to replace/append values to the data array(s). It's safer this way.

* fix_tox_conf(): Use ini_getval and ini_setval instead of modifying the original pointers directly

* Tests: Free resources

* Replace ini_getval(), ini_getval_required() and conv_*() usage

* Now using ini_getval_TYPE() functions and ini_setval()
* Remove unused helper functions and variables

* download() returns long, not int

* actions: update apt cache

* Fixes readout of packages in delivery

* Now that the overview is displayed after deferred packages are filtered out of the main list, filtered packages were no longer displayed
* This combines the main list and deferred list for both conda, and pip packages.

* Read the main and deferred lists no matter what

* Use new style package definition in test config
