Git ignored files cleanup.

Git ignored files cleanup.

Make gitignore entries not match recursively.

I wanted to introduce a directory "osdmaptool" to contain cli tests
for that tool, but all the files there were ignored because of these
rules.  Better be explicit about what you want ignored.

Move all ignores for generated binaries to be together.

Fixed "testecph" typo.

Added ignores for: testdout_streambuf testsignal_handlers testtimers.
