Eglot: abandon track-changes.el
After a ~10 month period of using track-changes.el as a support library
for tracking buffer changes, I've decided to go back to manually using
after-change-functions and before-change-functions.
track-changes.el showed promise:
- One of the selling points was to turn complicated a-c-functions and
b-c-functions into something easier, but that objectively didn't pan
out, with "virtual" positions, one-shot hooks, and tracker
registrations being abstractions and complications mastered by very
few.
- The other selling point was the ability to log and detect those parts
of Emacs that cheat the modification hooks and correct them. As far
as I can tell, only one such cheater -- quail.el -- was identified.
But with little consequence, only an ugly workaround in eglot.el (now
removed).
- After using Eglot daily for all this time, I didn't notice any
decrease in desynchronization events.
- I did notice an increase in track-changes.el related bugs, some of
which still baffle me and and hard to reproduce. A common occurence
is the '(cl-assertion-failed (memq id track-changes--trackers))'
which is hard to track down.
- The library makes it more complicated to run Eglot on older Emacsen.
I might yet revisit this matter for the next version but this
experience has shown that it didn't bring the advantages I thought it
would, so I'm abandoning it until at least 1.19 is out.

Remove redundant case_Lisp_Int macro
The case_Lisp_Int macro was originally introduced with different
definitions depending on USE_2_TAGS_FOR_INTS. However, since commit 2b5701247845, we have assumed that USE_2_TAGS_FOR_INTS is always
defined, and the macro has only a single definition. As a result, the
macro is now unnecessary, and replacing it with standard C case labels
improves readability and understanding.

Remove workaround for AIX 3.2 crashes
Emacs does not support AIX 3.2 since 2008.
This workaround for AIX 3.2.3 and 3.2.4 (released in 1992) was
introduced in 1999 and was only active with #ifdef AIX3_2. In 2008, the
condition was changed to #ifdef AIX when support for these older AIX
versions was dropped. I couldn't find any justification for why this
workaround was retained (instead of being removed) in the commit message
or mailing list archives.
Given that users of AIX 4.0 (released in 1995) or later have not had
this workaround for over a decade (1999-2008), it seems safe to assume
that it is no longer necessary. Removing it will also prevent the
incorrect overriding of the LANG variable on those systems.

Replace call[1-8] with calln
