Problem: regexp: max \U and \%U value is limited by INT_MAX but gives a
confusing error message (related: v8.1.0985).
Solution: give a better error message when the value reaches INT_MAX
When searching Vim allows to get up to 8 hex characters using the /\V
and /\%V regex atoms. However, when using "/\UFFFFFFFF" the code point is
already above what an integer variable can hold, which is 2,147,483,647.
Since patch v8.1.0985, Vim already limited the max codepoint to INT_MAX
(otherwise it caused a crash in the nfa regex engine), but instead of
error'ing out it silently fell back to parse the number as a backslash
value and not as a codepoint value and as such this "/[\UFFFFFFFF]" will
happily find a "\" or an literal "F". And this "/[\d127-\UFFFFFFFF]"
will error out as "reverse range in character class).
Interestingly, the max Unicode codepoint value is U+10FFFF which still
fits into an ordinary integer value, which means, that we don't even
need to parse 8 hex characters, but 6 should have been enough.
However, let's not limit Vim to search for only max 6 hex characters
(which would be a backward incompatible change), but instead allow all 8
characters and only if the codepoint reaches INT_MAX, give a more
precise error message (about what the max unicode codepoint value is).
This allows to search for "[\U7FFFFFFE]" (will likely return "E486
Pattern not found") and "[/\U7FFFFFF]" now errors "E1517: Value too
large, max Unicode codepoint is U+10FFFF".
While this change is straight forward on architectures where long is 8
bytes, this is not so simple on Windows or 32bit architectures where long
is 4 bytes (and therefore the test fails there). To account for that,
let's make use of the vimlong_T number type and make a few corresponding
changes in the regex engine code and cast the value to the expected data
type. This however may not work correctly on systems that doesn't have
the long long datatype (e.g. OpenVMS) and probably the test will fail
there.

Problem: font ligatures don't render correctly in the Win32 GUI-version
of gvim even when set rop=type:directx is used. Setting
guiligatures also doesn't make any difference. This leads to
broken font ligatures when the cursor passes through them. It
does not recover from this, and they remain broken until you
re-render the whole buffer (e.g. by using Ctrl+L).
Solution: the problem is that we only re-draw the current and previous
character in gui_undraw_cursor() and only have the special case
for GTK when it comes to rendering ligatures. So let's enable
gui_adjust_undraw_cursor_for_ligatures() to also happen for
Win32 GUI if guiligatures is setup correctly (all this does is
expand the range of gui_undraw_cursor() with ligature characters).

Problem: Autocmds triggered from opening the cmdwin (in win_split and
do_ecmd) can cause issues such as E199, as the current checks
are insufficient.
Solution: Commands executed from the cmdwin apply to the old curwin/buf,
so they should be kept in a "suspended" state; abort if
they've changed. Also abort if cmdwin/buf was tampered with,
and check that curwin is correct. Try to clean up the cmdwin
buffer (only if hidden and non-current to simplify things; the
same approach is used when closing cmdwin normally), and add a
beep. (Sean Dewar)
It'd be nice to also check that curwin was *really* created by win_split, as
autocommands can change curwin before it returns (so it can't be assumed to be
that of the split); for now, this means that the cmdwin may not be the botwin in
that case, which is probably OK.

Problem: [security] overflow in :history
Solution: Check that value fits into int
The get_list_range() function, used to parse numbers for the :history
and :clist command internally uses long variables to store the numbers.
However function arguments are integer pointers, which can then
overflow.
Check that the return value from the vim_str2nr() function is not larger
than INT_MAX and if yes, bail out with an error. I guess nobody uses a
cmdline/clist history that needs so many entries... (famous last words).
It is only a moderate vulnerability, so impact should be low.

Problem: trim(): hard to use default mask (partly revert v9.0.2040)
Solution: use default mask when it is empty
The default 'mask' value is pretty complex, as it includes many
characters. Yet, if one needs to specify the trimming direction, the
third argument, 'trim()' currently requires the 'mask' value to be
provided explicitly.
Currently, an empty 'mask' will make 'trim()' call return 'text' value
that is passed in unmodified. It is unlikely that someone is using it,
so the chances of scripts being broken by this change are low.
Also, this reverts commit 9.0.2040 (which uses v:none for the default
and requires to use an empty string instead).

Problem: No support for writing extended attributes
Solution: Add extended attribute support for linux
It's been a long standing issue, that if you write a file with extended
attributes and backupcopy is set to no, the file will loose the extended
attributes.
So this patch adds support for retrieving the extended attributes and
copying it to the new file. It currently only works on linux, mainly
because I don't know the different APIs for other systems (BSD, MacOSX and
Solaris). On linux, this should be supported since Kernel 2.4 or
something, so this should be pretty safe to use now.
Enable the extended attribute support with normal builds.
I also added it explicitly to the :version output as well as make it
able to check using `:echo has("xattr")`, to have users easily check
that this is available.
In contrast to the similar support for SELINUX and SMACK support (which
also internally uses extended attributes), I have made this a FEAT_XATTR
define, instead of the similar HAVE_XATTR.
Add a test and change CI to include relevant packages so that CI can
test that extended attributes are correctly written.

- In `get_lval()`, fill in `ll_object`/`ll_class`/`ll_oi` as needed; when no `[idx] or .key`, check lval_root on the way out.
- In `do_lock_var()` check for `ll_object`/`ll_class`; also bullet proof ll_dict case
and give `Dictionay required` if problem. (not needed to avoid lockvar crash anymore)
- In `compile_lock_unlock()` compile for the class variable and func arg cases.
