This is problematic as we don't have namespacing for these and some of
the macros can interfere with other defines.
This reverts commit 8634c7e349.

As weston_windowed_output_get_api needs ARRAY_LENGTH() move helpers to a
libweston/ so other users can re-use that instead of re-defining these
all over. Easier for other front-ends to make use of them.
With this change windowed-output-api.h also includes the helpers header.

Users like desktop-shell want to parse a provided string containing a
combination of environment and arg, e.g.: ENV=stuff /path/to/thing --good
Add support to custom-env for parsing this, with tests, so we can delete
the custom implementation inside desktop-shell.

execve() takes the same form for arguments as environment: an array of
constant pointers to mutable strings, terminated by a NULL.
To make it easier for users who want to build up their own argument
strings to pass to execve, add support for argument arrays to custom_env.

Rename the bits handling environment variables (currently, all of it),
so we have room to handle args as well.
No functional changes.
