fish shell 4.5.0

This is mostly a patch release for Vi mode regressions in 4.4.0 but other minor behavior changes are included as well.

This release comprises 68 commits since 4.4.0, contributed by 16 authors, 8 of which are new committers.

Interactive improvements

• ctrl-l no longer cancels history search (#12436).
• History search cursor positioning now works correctly with characters of arbitrary width.

Deprecations and removed features

• fish no longer reads the terminfo database to alter behaviour based on the TERM environment variable, and does not depend on ncurses or terminfo. The ignore-terminfo feature flag, introduced and enabled by default in fish 4.1, is now permanently enabled. fish may no longer work correctly on Data General Dasher D220 and Wyse WY-350 terminals, but should continue to work on all known terminal emulators released in the 21st century.

Regression fixes:

• (from 4.4.0) Vi mode d,f key binding did not work (#12417).
• (from 4.4.0) Vi mode c,w key binding wrongly deleted trailing spaces (#12443).
• (from 4.4.0) Vi mode crash on c,i,w after accepting autosuggestion (#12430).
• (from 4.4.0) fish_vi_key_bindings called with a mode argument produced an error (#12413).
• (from 4.0.0) Build on Illumos (#12410).
