- Checks for ECHOE, ICANON were left over from Vim code. We already
reference the symbols elsewhere without checking.
- newline_on_exit, intr_char: Both are vestigial remnants of Vim 4.x,
not implemented in Nvim. intr_char is a termios/stty feature, it's
probably not useful because users have other ways to configure their
terminals.

This option allows configuring what character is shown on the empty
lines at the end of a buffer, previously hardcoded to ‘~’

Store text in ScreenLines as UTF-8, so it can be sent as-is to the UI
layer. `utfc_char2bytes(off,buf)` is removed, as `ScreenLines[off]` now
already contains this representation.
To recover the codepoints that the screen arrays previously contained, use
utfc_ptr2char (or utf_ptr2char to ignore composing chars).
NB: This commit does NOT change how screen.c processes incoming UTF-8 data
from buffers, cmdline, messages etc. Any algorithm that operates on UCS-4
(like arabic shaping, treatment of non-printable chars)
is left unchanged for now.

silent-mode (-es/-Es) has been broken for years. The workaround up to
now was to include --headless. But --headless is not equivalent because
it prints all messages, not the limited subset defined by silent-mode.

Problem: A large count on a normal command causes trouble. (Dominique
Pelle)
Solution: Make "opcount" long.

Problem: No autocmd triggered in Insert mode with visible popup menu.
Solution: Add TextChangedP. (Prabir Shrestha, Christian Brabandt,
closes vim/vim#2372, closes vim/vim#1691)
Fix that the TextChanged autocommands are not always triggered
when sourcing a script.

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.

Based on screen.c code this value is not a boolean, so `false` is not
appropriate. It should be either 0 or one of DBCS_… values.

Should also fix some PVS warnings in process.

It's a micro-optimization; check path_is_absolute_path(autocmd_fname)
instead.
The main optimization (which is still in place) afforded by Vim 7.2.021
was to avoid resolving <afile> when it is not needed.

Most fonts should have these by now. Both are a significant visual
improvement.
- Vertical connecting bar `│` is used by tmux, pstree, Windows 7 cmd.exe
and nvim-qt.exe.
- Middle dot `·` works on Windows 7 cmd.exe, nvim-qt.exe.
For reference: tmux uses these chars to draw lines: │ ├ ─

This avoids an error message in async context, where it is not safe.

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