a17a815c87 Revert "Add vector of cleanup/termination events to be executed before quit"
This reverts commit 8c14f0f30f.

This list is not reliable - there are many ways for fish to quit that does not
invoke these functions. It's also not necessary since the history is correctly
saved on exec.

a1728d61af Report errors on invalid replacements in string replace
If the replacement in `string replace` is invalid, prior to this fix we would
enter into an infinite loop trying to parse it. Instead report errors correctly.

3a45cad12e Introduce fish_mutex_t wrapping std::mutex
Add a fish-specific wrapper around std::mutex that records whether it is
locked in a bool. This is to make ASSERT_IS_LOCKED() simpler (it can just
check the boolean instead of relying on try_lock) which will make Coverity
Scan happier.

Some details: Coverity Scan was complaining about an apparent double-unlock
because it's unaware of the semantics of try_lock(). Specifically fish
asserts that a lock is locked by asserting that try_lock fails; if it
succeeds fish prints an error and then unlocks the lock (so as not to leave
it locked). This unlock is of course correct, but it confused Coverity Scan.

ffebe74885 Support building on Solaris 11
Took care of remaining issues preventing fish from building on Solaris.
Mainly caused by some assumptions that certain defines are POSIX when
they are not (`NAME_MAX`).

Moved `NAME_MAX` defines to common.h - for some reason, it was being
defined in a cpp file (`env_universal_common.cpp`) even though it is used
in multiple source files.

Now compiles on Solaris 11 with GNU Make. Still some warnings because
fish was written with GNU getopt in mind and the Solaris version doesn't
use `const char *` but rather just `char *` for getopt values, but it
builds nevertheless.

Assuming this closes #3340

cb352317bd Simplify the cached_esc_sequences_t structure
The type cached_esc_sequences_t caches escape sequences, and is tasked
with finding an escape sequence that prefixes a given string. Before
this fix, it did so by storing the lengths of cached escape sequences,
and searching for substrings of that length. The new implementation
instead stores all cached escape sequences in a sorted vector, and uses
binary search to find the shortest escape sequence that is a prefix of
the input. This is a substantial simplification that also reduces
allocations.

d54fbddb11 Using XXHash64 for all wcstring unordered_map/set hashing
Since we are including XXHash32/64 anyway for the wchar_t* hashing,
we might as well use it.

Use arch-specific hash size and xxhash for all wcstring hashing

Instead of using XXHash64 for all platforms, use the 32-bit version
when running on 32-bit platforms where XXHash64 is significantly slower
than XXHash32 (and the additional precision will not be used).

Additionally, manually specify wcstring_hash as hashing method for
non-const wcstring unordered_set/map instances (the const varieties
don't have an in-library hash and so already use our xxhash-based
specialization when calling std::hash<const wcstring>).

e6bb7fc973 Silence unused result warnings on newer compilers
Newer versions of GCC and Clang are not satisfied by a cast to void,
this fix is adapted from glibc's solution.

New wrapper function ignore_result should be used when a function with
explicit _unused_attribute_ wrapper is called whose result will not be
handled.

We need a way to encode arbitrary strings into valid fish variable

In particular, eliminating the need to manipulate the locale.

e6e1805c5f another step in fixing issue #3985
This changes all of the builtins to behave like `string` to return
STATUS_INVALID_ARGS (121) if the args passed to the command don't make
sense. Also change several of the builtins to use the existing symbols
(e.g., STATUS_CMD_OK and STATUS_CMD_ERROR) rather than hardcoded "0"
and "1" for consistency and to make it easier to find such values in
the future.

This primarily replaces "STATUS_BUILTIN_OK" with "STATUS_CMD_OK" and
"STATUS_BUILTIN_ERROR" with "STATUS_CMD_ERROR". That is because we want
to make it clear these status codes are applicable to fish functions as
well as builtins. Future changes will make it easier to use these
symbols and values in functions.
