Notes regarding the removal of specific items:
- Aztec C: only on the Amiga.
- mch_check_win(): doesn't exist anymore.
- Comment in ex_cmds.c: It seems the context for this comment was
removed, but the comment was inadvertantly left alone.
A similar macro is defined in the Linux kernel [1].
To refactor the code I used a slightly modified Coccinelle script I found in
[2].

Adapt #1533 and #1596 to conform to upstream patch
(https://groups.google.com/forum/#!topic/vim_dev/vp0Lwo9f56s).
Problem: Since patch 7.4.232 "1,3s/\n//" joins two lines instead of
three.
(Eliseo Martínez) Issue 287
Solution: Correct the line count. (Christian Brabandt)
Also set the last used search pattern.
By "simple pointer" I mean a pointer that can be freed with a call to `free`
without leaking any member pointer.
This macro does exactly what `ga_clear_strings` does.
Problem : Command `s/\n//` is being translated into a call to do_join
with a count of 1. But do_join asserts its precondition count
>= 2, which is causing the program to abort.
Note : This in fact revealed bigger problems: generated join command
line count, as well as reported substitutions/lines were
wrong in several cases, since patch 7.4.232.
See:
[patch] http://markmail.org/message/vo7ruair5raccawp
[issue] https://code.google.com/p/vim/issues/detail?id=287
Solution : - Don't generate join command for single-line-range case.
- Make generated join command include:
* lines in range + 1, when range doesn't end at last line.
* lines in range, when range ends at last line.
- Make reported substitutions/lines always be
number-of-lines-joined - 1.
Problems : Assigned value is garbage or undefined @ 127.
Assigned value is garbage or undefined @ 152.
Diagnostic : Multithreading issues.
Rationale : Error could only occurr if global `enc_utf8` changed while
the function is executing.
Resolution : Use local copy of global var.
Since the introduction of the FOR_ALL_BUFFERS macro, 'sign unplace id'
without a buffer was only removing the sign from the first buffer rather
than all buffers, as described in the documentation.

Though this module is relatively small it has very clear boundaries.
The last argument for extracting `tempfile` was the errors which I got
when I was writing unittests for it: `cimport './src/nvim/fileio.h'`
does not work for some reason.
- temp_count is uint32_t now instead of long because it supposed to be
at most 999999999 (comment on line 5227) temporary files. The most
probably it was a long for compatibility with systems where int is
16-bit.
- Use "nvim" as prefix for temp folder name instead of "v"
- Remove unused parameter from vim_tempname
- use return value instead of open_req.result
- libuv uv_fs_open() returns `-errno` instead of always -1
- libuv always sets open_req.result to the return value, _except_ for OOM
where it only sets the return value. So always use the return value.
- replace calls to mch_open macro.
- update call sites expecting -1 error
This macro is used to append an element to a growable array. It replaces this
common idiom:
ga_grow(&ga, 1);
((item_type *)ga.ga_data)[ga.ga_len] = item;
++ga.ga_len;
