* Minor updates to the min & max cache sizes (16 & 64MB). Mostly to satisfy my power-of-two OCD.
* Purge broken on-disk cache files
* Optimize free RAM computations
* Start dropping LRU items when running low on memory before pre-rendring (hinting) pages in non-reflowable documents.
* Make serialize dump the most recently *displayed* page, as the actual MRU item is the most recently *hinted* page, not the current one.
* Use more accurate item size estimations across the whole codebase.
TileCacheItem:
* Drop lua-serialize in favor of Persist.
KoptInterface:
* Drop lua-serialize in favor of Persist.
* Make KOPTContext caching actually work by ensuring its hash is stable.
* Update log android to match the current issue template
* Fix GUI gdb frontends getting wrecked by the older glib library we ship w/
KOReader
* Slightly more aggressive valgrind defaults
It's slower, but interpreting results without leak-check=full ends up
costing more time than just running with it.
* Add a callgrind shortcut
* Use getopt instead of a hand-rolled hack for option parsing
* Make it clearer that complex args should be quoted
* Document prompt
* Add a Valgrind suppression file for libdrm/mesa on AMD hardware
Because mesa/libdrm isn't built w/ -D valgrind=enabled on Gentoo,
and Valgrind is very much not happy with mesa ;p.
* Allow toggling reader.lua's sane return mode
(Enabled automatically under gdb/valgrind).
Should hopefully weed out some noise from valgrind reports.
* Propagate reader.lua's return code
* Sim a few other common devices
* Handle assigning values to short options with an equal instead of a space, like the previous solution
(This is purely for backward compatibility purposes, this is a syntax that'd fail with the C getopt, too).
* Add gnu-getopt to the build requirement on macOS, because of course everything is terrible.
