Problem: A hashtab with many removed items is not cleaned up.
Solution: Re-hash a hashtab even when the size didn't change if too many
items were removed.

Problem: Reallocating hashtab when the size didn't change.
Solution: Bail out when the hashtab is already the desired size.

vim-patch:8.2.0559: clearing a struct is verbose
Problem: Clearing a struct is verbose.
Solution: Define and use CLEAR_FIELD() and CLEAR_POINTER().

Problem: Giving error messages is not flexible.
Solution: Add semsg(). Change argument from "char_u *" to "char *", also
for msg() and get rid of most MSG macros. (Ozaki Kiichi, closes
vim/vim#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.

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

move `call_shell` to misc1.c
Move some fns to state.c
Move some fns to option.c
Move some fns to memline.c
Move `vim_chdir*` fns to file_search.c
Move some fns to new module, bytes.c
Move some fns to fileio.c
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.
- The 'stripdecls.py' script replaces declarations in all headers by includes to
generated headers.
`ag '#\s*if(?!ndef NEOVIM_).*((?!#\s*endif).*\n)*#ifdef INCLUDE_GENERATED'`
was used for this.
- Add and integrate gendeclarations.lua into the build system to generate the
required includes.
- Add -Wno-unused-function
- Made a bunch of old-style definitions ANSI
This adds a requirement: all type and structure definitions must be present
before INCLUDE_GENERATED_DECLARATIONS-protected include.
Warning: mch_expandpath (path.h.generated.h) was moved manually. So far it is
the only exception.
Current type of some other parameters/variables can be improved:
- hashtab_T : ht_error : int -> bool.
- hash_clear_all() : off : int -> unsigned int.
- hash_clear_all() : todo : long -> size_t.
- hash_may_resize() : todo : int -> size_t.
hashtab.h:
- hash_T: long_u -> size_t.
In principle, a hash value could thought of as just an unsigned number
without size semantics (uint32_t or uint64_t). But it is used as
index at some places, and so, size_t is also eligible. Therea re some
places where assignments occur between hash_T and size_t variables, in
both directions. Therefore, if we define hash_T to be of a type having
a different width than that of size_t, we will have an incorrect
assignment somewhere that will require an assert/guard. So the most
sensible option here seems to do hast_T to be size_t too.
- hashtab_T.ht_mask: long_u -> hash_T.
Masks are used to be combined with hash_T values, so they should be of
the same type.
hashtab.c:
- hash_may_resize(): oldsize: long_u -> size_t.
- hash_may_resize(): newsize: long_u -> size_t.
- hash_may_resize(): newmask: long_u -> hash_T.
hashtab.h:
- Add missing includes.
- Move hash_T to the top and use it to define hashtab_T.
- Move hash_removed related definitions to the top, as they are used in
the definition of hashtab_T.
- Reformat multiline expression (start continuation with operator).
- Reformat function declaration into one single line.
hashtab.c:
- Use C99 style variable declarations (move declarations as near to
first-usage point as possible).
- Simplify oldarray/newarray computation.
- Simplify unneeded else branch.
- Remove redundant casts.
Move files from src/ to src/nvim/.
- src/nvim/ becomes the new root dir for nvim executable sources.
- src/libnvim/ is planned to become root dir of the neovim library.
