Problem: User doesn't notice file does not exist when swap file does.
Solution: Add a note that the file cannot be found. Make the "still
running" notice stand out.

Problem: Test doesn't search for a sentence. Still fails when searching for
start of sentence. (Dominique Pelle)
Solution: Add paren. Check for MAXCOL in dec().

Problem: Recovering does not work when swap file ends in .stz.
Solution: Check for all possible swap file names. (Elfling, closesvim/vim#2395,

Problem: Swap file warning for a file in a non-existing directory, if there
is another with the same file name. (Juergen Weigert)
Solution: When expanding the file name fails compare the file names.

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.
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.
Problem: The OptionSet autocommand event is not triggered when entering
diff mode.
Solution: use set_option_value() instead of setting the option directly.
Change the tests from old to new style. (Christian Brabandt)

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

Problem: On MS-Windows large files (> 2Gbyte) cause problems.
Solution: Use "off_T" instead of "off_t". Use "stat_T" instead of "struct
stat". Use 64 bit system functions if available. (Ken Takata)

Only the off_T changes are relevant, since all the "struct stat" usage
is abstracted by libuv.
