Fix various compiler warnings and minor issues (#362)
List of changes: - Fixed some -Wuninitialized warnings and removed some unused variables. - Removed the unused extern for B_login (re:d8eba9d1
). - The libcmd builtins and the vmalloc memfatal function now handle memory errors with 'ERROR_SYSTEM|ERROR_PANIC' for consistency with how ksh itself handles out of memory errors. - Added usage of UNREACHABLE() where it was missing from error handling. - Extend many variables from short to int to prevent overflows (most variables involve file descriptors). - Backported a ksh2020 patch to fix unused value Coverity issues (https://github.com/att/ast/pull/740). - Note in src/cmd/ksh93/README that ksh compiles with Cygwin on Windows 10 and Windows 11, albeit with many test failures. - Add comments to detail some sections of code.

- Removed a lot of dead ifdef code. - edit/emacs.c: Hide an assignment to avoid a -Wunused warning. (See also https://github.com/att/ast/pull/753, which removed the assignment because ksh2020 removed the !SHOPT_MULTIBYTE code.) - sh/nvdisc.c: The sh_newof macro cannot return a null pointer because it will instead cause the shell to exit if memory cannot be allocated. That makes the if statement here a no-op, so remove it. - sh/xec.c: Fixed one unused variable warning in sh_funscope(). - sh/xec.c: Remove a fallthrough comment added in commited478ab7
because the TFORK code doesn't fall through (GCC also produces no -Wimplicit-fallthrough warning here). - data/builtins.c: The cd and pwd man pages state that these builtins default to -P if PATH_RESOLVE is 'physical', which isn't accurate: $ /opt/ast/bin/getconf PATH_RESOLVE physical $ mkdir /tmp/dir; ln -s /tmp/dir /tmp/sym $ cd /tmp/sym $ pwd /tmp/sym $ cd -P /tmp/sym $ pwd /tmp/dir The behavior described by these man pages isn't specified in the ksh man page or by POSIX, so to avoid changing these builtin's behavior the inaccurate PATH_RESOLVE information has been removed. - Mamfiles: Preserve multi-line errors by quoting the $x variable. This fix was backported from 93v-. (See also <a7e9cc82
>.) - sh/subshell.c: Remove set but not used sp->errcontext variable.
