- CMake features

We already set back_color_erase in our builtin terminfo
(terminfo_defs.h:conemu_terminfo), so we don't need to set it explicitly
in patch_terminfo_bugs().

- Also remove feature-detection of uv_set_vterm_state(): instead, on
  Windows we always require libuv to have that function.

Problem:    Needlessly searching for tilde in string.
Solution:   Only check the first character. (James McCoy, closes vim/vim#3734)

Problem:    An "after" directory of a package is appended to 'rtp', which
            will be after the user's "after" directory. ()
Solution:   Insert the package "after" directory before any other "after"
            directory in 'rtp'. (closes vim/vim#3409)
https://github.com/vim/vim/commit/99396d4cbf78d313a454c7448acc07412d2e45b7

Problem:    Package directory not added to 'rtp' if prefix matches.
Solution:   Check the match is a full match. (Ozaki Kiichi, closes vim/vim#2817)
            Also handle different ways of spelling a path.
