Adds a new feature to :autocmd which sets the handler to be executed at
most one times.
Before:
augroup FooGroup
autocmd!
autocmd FileType foo call Foo() | autocmd! FooGroup * <buffer>
augroup END
After:
autocmd FileType foo once call Foo()

> There already is an exception if writing to a “device” (e.g. FIFO).
> It makes sense to ignore certain errors like ENOTSUP or EOPNOTSUPP

Note about shada.c:
- shada_read_next_item_start was intentionally shadowing `unpacked` and
`i` because many of the macros (e.g. ADDITIONAL_KEY) implicitly
depended on those variable names.
- Macros were changed to parameterize `unpacked` (but not `i`). Macros
like CLEAR_GA_AND_ERROR_OUT do control-flow (goto), so any other
approach is messy.
Problem: Using an external diff program is slow and inflexible.
Solution: Include the xdiff library. (Christian Brabandt)
Use it by default.

Problem: When making backups is disabled and conversion with iconv fails
the written file is truncated. (Luo Chen)
Solution: First try converting the file and write the file only when it did
not fail. (partly by Christian Brabandt)

Problem: Saving the redo buffer only works one time, resulting in the "."
command not working well for a function call inside another
function call. (Ingo Karkat)
Solution: Save the redo buffer at every user function call. (closesvim/vim#1619)

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

Vim has the 'swapsync' option which we removed in 62d137ce09.
Instead let 'fsync' control swapfile-fsync.
These cases ALWAYS force fsync (ignoring 'fsync' option):
- Idle (CursorHold).
- Exit caused by deadly signal.
- SIGPWR signal.
- Explicit :preserve command.
Fixes#6890 by reading from the Windows console input buffer after
stdin has been closed.
Vim defines HAVE_DUP for Windows and does the close-dup dance[1]:
close(0);
dup(2);
which always fails, then falls back to reading from the Windows console
input buffer[2].

The implementation of vim_fgets() differs between Neovim and Vim.
Vim says that it only returns `true` for EOF. But it always returns `true` when
fgets() returns NULL. This happens for EOF _or_ errors.
That probably misguided the author of Neovim's vim_fgets(), which does NOT
return `true` for errors.
Since all the callers of vim_fgets() probably expect it to work as it does in
Vim (and not as it says), it now returns the same values as the Vim
implementation.
Fixes#8227
Problem: Loading file type detection slows down startup.
Solution: Store the last pattern of an autocommand event to make appending
quicker.

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.
