Speed up minaccept by only linting changed files

[Aaron Wells]

"make push" takes a long time to finish on my computer. On my laptop at home, just one small change takes about 48 seconds to run through minaccept. I've found myself more frequently just doing "git push gerrit HEAD:refs/publish/master" rather than waiting for it to finish.

So, I decided to see if I could speed things up. And it seems the biggest use of time in the minaccept is that it runs "php -l" on every PHP file in htdocs, not just the ones that have changed. Same for xmllint on all the XML files, but that's not as big of a problem because there aren't as many of them.
