Problem: More problems reported by coverity.
Solution: Avoid the warnings. (Christian Brabandt)

Applied manually. Files that do not exst anymore: gui.c gui_w16.c gui_w32.c
if_xcmdsrv.c os_unix.c
New ex commands: 'tcd', 'tchdir'
Changed Vimscript functions: 'haslocaldir', 'getcwd'
The ex-commands ':tcd' and ':tchdir' are the tab-local equivalents of
':lcd' and ':lchdir'. There are no new Vimscript functions introduced,
instead the functions 'haslocaldir' and 'getcwd' take in optional
arguments. See the documentation for details
Since there is now different levels of local directory a simple boolean
at source level is no longer sufficient; a new enumeration type is used
for the scope-level from now on.
The documentation has been accommodated for these new commands and
functional tests have been written to test the feature.
Problem: Crash when dragging with the mouse.
Solution: Add safety check for NULL pointer. Check mouse position for valid
value. (Hirohito Higashi)

Problem: Illegal memory access when using :copen and :cclose.
Solution: Avoid that curbuf is invalid. (suggestion by Justin M. Keyes)
Add a test.

Problem: ":tabmove" does not work as documented.
Solution: Make it work consistently. Update documentation and add tests.

Regarding the individual items in the header:
`Vim - Vi improved by Bram Moolenar`
Bram Moolenar is already mentioned throughout the documentation, as
well as the intro screen.
`:help uganda`
It's already shown to all users who don't use `shortmess+=I` upon
starting nvim, and is already placed prominently in help.txt, i.e.,
`:help` run with no arguments.
`:help credits`
Already mentioned near the top of help.txt.
`README.md`
Already mentioned in develop.txt.
What works:
1. ShaDa file dumping: header, registers, jump list, history, search patterns,
substitute strings, variables.
2. ShaDa file reading: registers, global marks, variables.
Most was not tested.
TODO:
1. Merging.
2. Reading history, local marks, jump and buffer lists.
3. Documentation update.
4. Converting some data from &encoding.
5. Safer variant of dumping viminfo (dump to temporary file then rename).
6. Removing old viminfo code (currently masked with `#if 0` in a ShaDa file for
reference).
When splitting the window (win_split_ins), function win_new_width is
already called before the height has been set. This calls
terminal_resize, which passes a height of 0 on to libvterm, which
doesn't handle a height of 0 properly.
A fix is already in place in terminal.c for not passing on the height,
but strictly speaking, it doesn't make sense for window to call
terminal_resize when it isn't initialized completely yet.
Problem: Window drawn wrong when 'laststatus' is zero and there is a
command-line window. (Yclept Nemo)
Solution: Set the status height a bit later. (Christian Brabandt)

We already use wrappers for allocation, the new `xfree` function is the
equivalent for deallocation and provides a way to fully replace the malloc
implementation used by Neovim.
Problem : Dereference of null pointer @ 1769.
Diagnostic : Real issue.
Rationale : It seems buffer could be null. Not sure, though.
Resolution : Check for buffer null.
This resolution was chosen as it will always work.
But it could be that buffer can't really be null at that
point. autocmd_win is ruled out by close_window, so that
can't be the case. I'm not sure if other windows without
buffers are possible, so leaving it this way.
If it's confirmed buffer can't be null, resolution through
an assert would be possible and this would be FP, not RI.
This commit integrates libvterm with Neovim and implements a terminal emulator
with nvim buffers as the display mechanism. Terminal buffers can be created
using any of the following methods:
- Opening a file with name following the "term://[${cwd}//[${pid}:]]${cmd}"
URI pattern where:
- cwd is the working directory of the process
- pid is the process id. This is just for use in session files where a pid
would have been assigned to the saved buffer title.
- cmd is the command to run
- Invoking the `:terminal` ex command
- Invoking the `termopen` function which returns a job id for automating the
terminal window.
Some extra changes were also implemented to adapt with terminal buffers. Here's
an overview:
- The `main` function now sets a BufReadCmd autocmd to intercept the term:// URI
and spawn the terminal buffer instead of reading the file.
- terminal buffers behave as if the following local buffer options were set:
- `nomodifiable`
- `swapfile`
- `undolevels=-1`
- `bufhidden=hide`
- All commands that delete buffers(`:bun`, `:bd` and `:bw`) behave the same for
terminal buffers, but only work when bang is passed(eg: `:bwipeout!`)
- A new "terminal" mode was added. A consequence is that a new set of mapping
commands were implemented with the "t" prefix(tmap, tunmap, tnoremap...)
- The `edit` function(which enters insert mode) will actually enter terminal
mode if the current buffer is a terminal
- The `put` operator was adapted to send data to the terminal instead of
modifying the buffer directly.
- A window being resized will also trigger a terminal resize if the window
displays the terminal.
Problem : Use after free @ 1795.
Diagnostic : Real issue.
Rationale : prev_curtab can in fact be freed as a result of call
`win_close_othertab(win, free_buf, prev_curtab);`, but it's
later used at
`sprintf(..., tabpage_index(prev_curtab));`.
This was introduced at
3ffc5d81c3.
Resolution : Move prev_idx calculation before the call freeing
prev_curtab.
- Removed term.c, term.h and term_defs.h
- Tests for T_* values were removed. screen.c was simplified as a
consequence(the best strategy for drawing is implemented in the UI layer)
- Redraw functions now call ui.c functions directly. Updates are flushed with
`ui_flush()`
- Removed all termcap options(they now return empty strings for compatibility)
- &term/&ttybuiltin options return a constant value(nvim)
- &t_Co is still available, but it mirrors t_colors directly
- Remove cursor tracking from screen.c and the `screen_start` function. Now the
UI is expected to maintain cursor state across any call, and reset it when
resized.
- Remove unused code
Problem: In some situations, when setting up an environment to trigger an
autocommand, the environment is not properly restored.
Solution: Check the return value of switch_win() and call restore_win()
always. (Daniel Hahler)

Regarding dict_lookup() in eval.c: both definitions are the same, the
only difference being the spacing between the indirection operator and
the indentation level.
Problem : getdigits() currently returns a long, but at most places,
return value is casted (unsafely) into an int. Making casts
safe would introduce a lot of fuss in the form of assertions
checking for limits.
Note : We cannot just change return type to int, because, at some
places, legitimate long values are used. For example, in
diff.c, for line numbers.
Solution : Introduce new functions:
- get_digits() : Gets an intmax_t from a string.
- get_int_digits() : Wrapper for ints.
- get_long_digits() : Wrapper for longs.
And replace getdigits() invocations by the appropiate
wrapper invocations.
Problem: ":sign jump" may use another window even though the file is
already edited in the current window.
Solution: First check if the file is in the current window. (James McCoy)
