For the case of Clojure and other Lisp syntax highlighting, it is
necessary to create huge regexps consisting of hundreds of symbols with
the pipe (|) character. To make things more difficult, these Lisp
symbols sometimes consists of special characters that are themselves
part of special regexp characters like '*'. In addition to being
difficult to maintain, it's performance is suboptimal.
This patch introduces a new predicate to perform 'source' matching in
amortized constant time. This is accomplished by compiling a hash table
on the first use.
Problem: Delete() can not handle a file name that looks like a pattern.
Solution: Use readdir() instead of appending "/*" and expanding wildcards.

Since the providers are ordered by ns_id, inserting a new provider may
require shifting existing providers around to maintain this ordering.
When this happens, we need to allocate a new element at the end of the
vector and then shift the larger elements to the right. Rather than
iterating (incorrectly) with a loop and copying each item, use memmove
to copy the entire block.
This commit prevents two things regarding the tagstack and jumping to
locations:
- Pushing the same item twice in a row
- Pushing an item where the destination is the same as the source
Both prevent having to press CTRL-T additional times just to pop items
that don't make the cursor move.
There were a couple of reports of "Buffer X newer than edits" problems.
We first assumed that it is incorrect for a server to send 0 as a
version - and stated that they should send a `null` instead, given that
in the specification the `textDocument` of a `TextDocumentEdit` is a
`OptionalVersionedTextDocumentIdentifier`.
But it turns out that this was a change in 3.16, and in 3.15 and earlier
versions of the specification it was a `VersionedTextDocumentIdentifier`
and language servers didn't have a better option than sending `0` if
they don't keep track of the version numbers.
So this changes the version check to always accept `0` values.

It looks solid with the default `FloatBorder` group.
If you set the bgcolor of FloatBorder to the same color as for FloatNormal, you
effectively get an "1-cell padding".
Replacement for Vim's test_null_string().
Vim uses it to verify that its codebase handles null strings.
Preparation for the Test_null_list() in patch v8.2.1822.
Use v:_null_string, not non-existent env var, for null string tests.
Mention v:_null_string in id() because id(v:_null_string) returns (nil).
