dirt 1.0 (new formula)

An unimpressive thingie for playing bits of samples with some level of
accuracy. Dirt is a software sampler, which listens for
OpenSoundControl messages on port 7771. Mainly used with Tidal
(http://yaxu.org/tidal/). Released as free software under the terms of
the GNU Public License version 3.0 and later.

brew: error out if bad xcode-select path given

Since a bad xcode-select path can cause many brew commands to freeze,
it's worth warning users and bailing out as early as possible.

The doctor check wasn't good enough, since the doctor could freeze
before the warning about this was ever printed.

fix repo URL for brew search

xcode-select check: move after first options
Pathname#extname returns a string
keg: use lib helper
keg: try to avoid disk IO when possible

Calling Pathname#text_executable? reads in the first 1024 bytes of the
file, so try the basename check (which requires no filesystem access)
first.
keg: factor out dylib id calculation
keg: decouple dylib id changes from install name changes

The dylib id calculation does not use any information gathered in
install_names_for, so we can pull the logic out completely and only
yield the install names.
