Consistent processing of file extensions, as described in the previous
commit, has been applied to the 'which' applet and the functions
find_executable and mingw_spawn_interpreter.
In spawnveq check that the file to be executed exists and is executable,
and ensure that it won't have any extensions added by spawnve.
It's intended that all files passed to spawnve should have their names
fully specified. If this isn't the case the tests here will cause errors
which will need to be fixed.

Move the code to detect shell scripts and binary executables from
mingw_access to a separate function, has_exec_format. Call this function
in do_lstat to decide whether to set the executable bits in the file mode.
This will slow down stat but has a couple of advantages:
- shell scripts are highlighted in ls output
- the test applet can use stat(2) to detect executable files
The new function is used to handle another corner case in spawnveq:
binary executables without the usual .exe extension are only run by
spawnve if the file name ends with '.'.
Two minor changes:
- file_is_win32_executable has been renamed add_win32_extension to
clarify what it does
- a call to file_is_executable has been removed from find_command
in ash as it resulted in unhelpful error messages.
