Eglot: use eglot-advertise-cancellation in more situations

The async requests frequently issued by ElDoc are a significant
source of request pile-up on the server side (for some servers).

With this change, Eglot will issue additional LSP
$/cancelRequest notifications for in-flight requests of certain
kinds in the pre-command hook.

This required a small change to the 'jsonrpc-async-request'
entrypoint.

This feature is experimental.

* lisp/jsonrpc.el (jsonrpc-async-request): No longer returns nil.

* lisp/progmodes/eglot.el (eglot--inflight-async-requests): New variable.

(Ftranspose_regions): Fix text-properties for len1==len2

When `len1_byte == len2_byte`, the code presumed that len1==len2
as well in its handling of text-properties.  Fix that case.
While at it, try and reduce code duplication by hoisting common
code out of `if`s, and throw away the optimization for `len_mid == 0`
which only saved 3 trivial function calls.

* src/editfns.c (Ftranspose_regions): Shuffle the code a bit.

* test/src/editfns-tests.el (editfns-tests--transpose-equal-but-not):

Mark kermit.el as obsolete

While Kermit is still developed, this Emacs support library is
essentially unchanged since it was added to Emacs, which seems to have
been in 1988.  It is also based on the old pre-Emacs 20 shell mode, so
it's not clear if it even works, and much less if it is relevant with
Kermit from this century.

There is also this modern alternative, from 1994, which seems far
more complete: https://www.kermitproject.org/archive.html#emacs

The bug tracker has stayed silent, so if anyone is still using it, they
will have to report a bug and ask us to unobsolete it.

* lisp/obsolete/kermit.el: Add Obsolete-since header.  Add link to
alternative library at kermitproject.org.
