Problem: When 'hlsearch' is set and matching with the last search pattern
is very slow, Vim becomes unusable. Cannot quit search by
pressing CTRL-C.
Solution: When the search times out set a flag and don't try again. Check
for timeout and CTRL-C in NFA loop that adds states.

uninitialized buffer pointer. (Kuang-che Wu)
Solution: Set rex.reg_buf when compiling the pattern. (closesvim/vim#3972)

tigetstr (used by libtermkey/driver-ti.c) may return -1 as a pointer.
Documented in man 3 tigetstr. https://linux.die.net/man/3/tigetstr
> The tigetstr routine returns the value (char *)-1 if capname is not a string
> capability, or 0 if it is canceled or absent from the terminal description.

Problem: Pattern with syntax error gives threee error messages. (Kuang-che
Wu)
Solution: Remove outdated internal error. Don't fall back to other engine
after an error.

Note: the test fails on non-Windows CI (Travis linux, Quickbuild bsd):
even on master before the env.c changes in this patch-series.
Maybe the unix part of printenv-test.c needs to be revisited.

- Minimum required libuv is now v1.12
- Because `uv_os_getenv` requires allocating, we must manage a map
(`envmap` in `env.c`) to maintain the old behavior of `os_getenv` .
- free() map-items after removal. khash.h does not make copies of
anything, so even its keys must be memory-managed by the caller.

It's reported that the Windows widechar variants do automatically
convert from the current codepage to UTF16, which is very helpful. So
the "widechar" impls are a good direction. But libuv v1.12 does that
for us, so the next commit will use that instead.

Problem: Mode() does not indicate using CTRL-O from Insert mode.
Solution: Add "niI", "niR" and "niV" to mode() result. (closesvim/vim#3000)

Problem: Sorting large numbers is not tested and does not work properly.
Solution: Add test. Fix comparing lines with and without a number.

- Like Vim, use set_option_value() followed by reset_option_was_set().
- Do not use set_string_default(), so the default is predictable.
This affects `:set bg&`.
- Wait until end-of-startup (VimEnter) to handle the response. The
response is racey anyways, so timing is irrelevant. This allows
OptionSet to be triggered, unlike during startup.
