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).
Problem: Highlighting for :s wrong when using different separator.
Solution: Use separat argument for search direction and separator. (Rob

Problem: Status line is not updated when going to cmdline mode.
Solution: Redraw status lines if 'statusline' is set and going to status
line mode. (based on patch from Justin M. Keyes et al.,
closesvim/vim#8044)
