blackbox: guard against recursion from dirty check

tests: divorce blackbox test from test-dispatch.py I used test-dispatch.py to demonstrate what would happen if a log file changed from being readonly to writable, by having it replace a directory (proxy for readonly/not-writable) with a log file in between transactions of a running python process (proxy for Mercurial). This commit makes it easier for people to follow what the test is doing, by creating a real file that people can read.

tests: test-dispatch use print_function

tests: test-dispatch use absolute_import

templater: ignore orig/rej files If your mercurial/templates/ directory is dirty, then the template system would otherwise import duplicate templates from the .orig files and potentially try to parse .rej files. Since editing/reverting these templates isn't an unexpected action, and since they're in .hgignore, it's best that the template system know to skip them."

resolve: when pats do not match, hint about path: Suggest a command that would probably work.

shelve: changes getting opts values by get method When shelve is used by another extension that doesn't provide all necessary values in opts shelve raises KeyError exception. This patch fixes this by getting values from opts dictionary with get method.

contrib: remove references to 2to3 The custom porting fixers are removed. A comment related to 2to3 has been removed from the import checker. After this patch, no references to 2to3 remain.

check-code: remove redundant import style check We have a dedicated tool that checks for import conventions. Remove a redundant and less powerful check.
