Tidy up some #include lines.

Add support for 'name' and 'use' which allows more of the latest magic
files to work unchanged. (We are still missing 'indirect' and a few
other bits.)

Add support for 'clear' test, and fix 'default' to expand the result
string if any (used by, for example, rtf).

Fix the default type to work properly, that is to only match if no
previous test at the same level has matched.

Add support for !:strength modifier to adjust strength of a test.

Offset into the file can be size_t and add some casts to remove warnings.

use limits.h instead of sys/param.h to get PATH_MAX

Support = test for floats and doubles.

Add another function for printing warnings before the magic_line is
created so all warnings go through the same fprintf.

I got confused and made the strength multiplier 20, it should be 10.

New implementation of the file(1) utility. This is a simplified,
modernised version with a nearly complete magic(5) parser but omits some
of the complex builtin tests (notably ELF) and has a reduced set of
options.

file update to 4.24

The '-i' switch is now enabled so file(1) can output mime type strings.
