Problem: ruby#Detect() and node#Detect() don't return a [prog, err] pair
which means callers must special-case them.
Solution: align their return signatures with the perl/pythonx providers.
* support for :perl, :perlfile, :perldo and perleval()
* document that the perl provider doesn't currently work on Windows
* document that the perl legacy interface is now also supported
* added perleval() documentation
* import legacy perl interface tests
* only perl 5.22+ is supported
* healtcheck: use g:perl_host_prog if its set instead
using just 'perl' isn't correct as it may not be the version requested.
ditto for 'cpanm', rather go through 'App::cpanminus' to find the latest
perl version

This caused segfaults when calling win_findbuf in an `on_detach`
callback, when the callback was triggered when closing the last window
containing the buffer.
- remove redundant autocmd list
This "grouped" list is useless, it only gets in the way when searching
for event names.
- intro.txt: cleanup
- starting.txt: update, revisit
- doc: `:help bisect`
- mbyte.txt: update aliases 1656367b90. closes#11960
- options: remove 'guifontset'. Why:
- It is complicated and is used by almost no one.
- It is unlikely to be implemented by Nvim GUIs (complicated to parse,
specific to Xorg...).
If set the number of history saves is 0, assertions fail when inserting an entry on exit.
Dont insert an entry when the number of saves is 0 fixes the issue.
fixes#11497
Can be reproduced with a script like this:
-- in some lua file
vim.fn.timer_start(10, function() error("uh....") end)
-- will cause neovim to crash with the following error.
PANIC: unprotected error in call to Lua API
(nlua_CFunction_func_call failed.)
After this, it will instead print the error message
from the top of the stack, like so.
tmp/error_nvim.lua:10: uh...
Also added an example test. Previously this test
caused the embedded nvim to panic.

* Reuse inccommand preview window
Currently, show_sub (inside ex_substitute) creates a new split on each
run for its existing buffer, and ex_substitute calls close_windows for
it. This functionality seems to relay in delayed operations on window
structures where the close event on the newest window is "cancelled" by
win_grid_alloc. But for multigrid, there is optimization in place in
win_grid_alloc which causes any (unnecessary?) allocations to be
skipped, and thus inccommand preview window is not preserved but closed
immediately. Alternative fix would be to remove said optimization, but
the whole "lets create a new split each time and trash the earlier
window" seems too wasteful.
Fix#11529
* Update failing test
The failing test sets inccommand=split and does `:%s/.`, but isn't
expecting to get any contents for the preview window, other than the
windows status line. Update the test to include the preview window
contents too.

I think I have also opened up the possibility for people to use these
callbacks elsewhere, since I've added a new struct that we should be
able to use.
Also, this should allow us to determine what the state of a list is in
Lua or a dictionary in Lua, since we now can track the luaref as we go.
