Problem: too many strlen() calls
Solution: Change expand_env() to return string length
(John Marriott)
This commit does the following changes:
- In expand_env_esc():
- return the length of the returned dst string.
- refactor to remove some calls to STRLEN() and STRCAT()
- add check for out-of-memory condition.
- Change call sites in various source files to use the return value

Problem: MS-Windows: Compiler warnings
Solution: Resolve size_t to int warnings
closes: #14874
A couple of warnings in ex_docmd.c have been resolved by modifying their
function argument types, followed by some changes in various function
call sites. This also allowed removal of some casts to cope with
size_t/int conversion.

Problem: Dynamic loading of libsodium not handled properly.
Solution: Fix has() and :version. Show an error message when loading fails.
Fix memory leaks. (Ken Takata, closes#9754)
Problem: CodeQL reports problem in if_cscope causing it to fail.
Solution: Use execvp() instead of execl(). Merge the header file into the
source file. (Ozaki Kiichi, closes#9519)
Problem: Vim9: argument types are not checked at compile time.
Solution: Add several more type checks. Fix type check for matchaddpos().
(Yegappan Lakshmanan, closes#8619)
Problem: assert_fails() checks the last error message.
Solution: Check the first error, it is more relevant. Fix all the tests
that rely on the old behavior.
Problem: The evalfunc.c file is still too big.
Solution: Move f_pathshorten() to filepath.c. Move f_cscope_connection() to
if_cscope.c. Move diff_ functions to diff.c. Move timer_
functions to ex_cmds2.c. move callback functions to evalvars.c.
Problem: Alloc() returning "char_u *" causes a lot of type casts.
Solution: Have it return "void *". (Mike Williams) Define ALLOC_ONE() to
check the simple allocations.
Problem: Using "int" for alloc() often results in compiler warnings.
Solution: Use "size_t" and remove type casts. Remove alloc_check(), Vim
only works with 32 bit ints anyway.
Problem: Cannot recover from a swap file.
Solution: Do not expand environment variables in the swap file name.
Do not check the extension when we already know a file is a swap
file. (Ken Takata, closes 4415, closes#4369)
Problem: Macros for MS-Windows are inconsistent, using "32", "3264 and
others.
Solution: Use MSWIN for all MS-Windows builds. Use FEAT_GUI_MSWIN for the
GUI build. (Hirohito Higashi, closes#3932)
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
#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.
Problem: FEAT_WINDOWS adds a lot of #ifdefs while it is nearly always
enabled and only adds 7% to the binary size of the tiny build.
Solution: Graduate FEAT_WINDOWS.
