* 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
