Problem: Asking about existing swap file unnecessarily.
Solution: When it is safe, delete the swap file. Remove
HAS_SWAP_EXISTS_ACTION, it is always defined. (closesvim/vim#1237)

vim-patch:8.0.1279: initializing menus can be slow
Problem: Initializing menus can be slow, especially when there are many
keymaps, color schemes, etc.
Solution: Do the globbing for runtime files lazlily. (Ken Takata)

On today's systems these values are huge (4GB in my machine with 8GB of RAM
since it's set as half the available memory by default) 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
swapping mechanism. This is unnecessary and inefficient since the operating
system already virtualized the 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.

Also added stubs for 'cryptmethod' and 'key', and placeholders for
explanation regarding removal of crypto functionality.
