Apple clang version 14.0.0 (clang-1400.0.17.3.1) fails the build
because stds.h defines `fallthrough` as a macro which is then
expanded when base.h evaluates
# if __has_attribute(fallthrough) && __clang_major__ >= 5
The macOS SDK defines `DISPATCH_FALLTHROUGH` as the macro instead
of `fallthrough`.
This change replaces the use of `fallthrough` in the tree with
`HEIM_FALLTHROUGH` and updates the declaration in configure logic
to define `HEIM_FALLTHROUGH` based upon existing definitions
(if any) of `fallthrough` or `DISPATCH_FALLTHROUGH`.
The pseudo keyword 'fallthrough' is defined such that case statement
blocks must end with any of these keywords:
* break;
* fallthrough;
* continue;
* goto <label>;
* return [expression];
*
* gcc: https://gcc.gnu.org/onlinedocs/gcc/Statement-Attributes.html#Statement-Attributes
The macro is defined either as
__attribute__((__fallthrough__))
or as
do {} while (0) /* fallthrough */
not including the semicolon.
This change implements the Linux kernel style and updates several locations
where "/*fallthrough*/ and /* FALLTHROUGH */ were not previously replaced.
Externally imported code such as libedit, libtommath and sqlite are
restored to their unaltered state.

95eb83c424 ("roken: Add roken_get_username() and friends")
failed to copy the username C-String NUL terminator. As a result
a "DOMAIN\user" is returned as "userIN\user".

When WIN32 is undefined an unreachable code warning was generated
since "/bin/sh" is returned as the default resposne.

We add roken_get_{shell, username, appdatadir, homedir}() functions. These use
a combination of secure_getenv(), getpwuid_r(), getlogin_r(), or various WIN32
functions to get this information.
Use roken_get_appdatadir() instead of roken_get_homedir() when looking for
dotfiles.
