Problem: Problems with autocommands when opening help.
Solution: Avoid using invalid "varp" value. Allow using :wincmd if buffer
is locked. (closesvim/vim#1806, closesvim/vim#1804)

Problem: When setting the cterm background with ":hi Normal" the value of
'background' may be set wrongly.
Solution: Check that the color is less than 16. Don't set 'background' when
it was set explicitly. (Lemonboy, closesvim/vim#1710)

Problem: Swap file exists briefly when opening the command window.
Solution: Set the noswapfile command modifier before splitting the window.

Problem: ":set scroll&" often gives an error.
Solution: Don't use a fixed default value, use half the window height. Add a
test. (Ozaki Kiichi, closesvim/vim#2104)

Problem: Double free when compiled with EXITFREE and setting 'ttytype'.
Solution: Avoid setting P_ALLOCED on 'ttytype'. (Dominique Pelle,

Make `:verbose set ...` show when an option was last modified by an
API client or Lua script/chunk. In the case of an API client, the
channel ID is displayed.
After this change we never release blocks from memory (in practice it
never happened because the memory limits are never reached). Let the OS
take care of that.
---
On today's systems the 'maxmem' and 'maxmemtot' values are huge (4+ GB)
so the limits are never reached in practice, but Vim wastes a lot of
time checking if the limit was reached.
If the limit is reached Vim starts saving pieces of the swap file that were in
memory to the disk. Said in a different way: Vim implements its own
memory-paging mechanism. This is unnecessary and inefficient since the
operating system already has virtual memory and will swap to the disk if
programs start using too much memory.
This change does...
1. Reduce the number of config options and need for documentation.
2. Make the code more efficient as we don't have to keep track of memory
usage nor check if the memory limits were reached to start swapping
to disk every time we need memory for buffers.
3. Simplify the code. Once memfile.c is simple enough it could be
replaced by actual operating system memory mapping (mmap,
MemoryViewOfFile...). This change does not prevent Vim to recover
changes from swap files since the swapping code is never triggered
with the huge limits set by default.
Problem: Crash when closing the quickfix window in a FileType autocommand
that triggers when the quickfix window is opened.
Solution: Save the new value before triggering the OptionSet autocommand.
Add the "starting" flag to test_override() to make the text work.

Problem: When running :make the output may be in the system encoding,
different from 'encoding'.
Solution: Add the 'makeencoding' option. (Ken Takata)

Problem: Cannot make Vim fail on an internal error.
Solution: Add IEMSG() and IEMSG2(). (Domenique Pelle) Avoid reporting an
internal error without mentioning where.

Unix's typical locale-related environment variables aren't always set
appropriately on a Mac. Instead of relying on them, query the locale
information using Mac specific APIs and then set $LANG appropriately for
the rest of nvim.
Closes#5873
Get terminal debugging info by starting Nvim with 'verbose' level 3:
nvim -V3log
This is like Vim's `:set termcap`, which was removed in Nvim (and would
be very awkward to restore because of the decoupled UI).
Since "builtin" terminfo definitions were implemented (7cbf52db1b),
the decisions made by tui.c and terminfo.c are more relevant. Exposing
that decision in the 'term' option helps with troubleshooting.
Also: remove code that allowed setting t_Co. `:set t_Co=…` has never
worked; the highlight_spec test asserting that nvim_set_option('t_Co')
_does_ work makes no sense, and should not have worked.
