debug: move extensions debug behind a dedicated flag...

debug: move extensions debug behind a dedicated flag Since b86664c81833, we process the `--debug` flag earlier. This is overall good and useful, but has at least one negative side effect. Previously the debug message we report when trying to import extensions were issued before we processed the `--debug` flag. Now they happen after. Before: $ ./hg id --debug tip After: $ ./hg id --debug ☿ (revset-bench) could not import hgext.evolve (No module named evolve): trying hgext3rd.evolve could not import hgext.mercurial_keyring (No module named mercurial_keyring): trying hgext3rd.mercurial_keyring could not import hgext3rd.mercurial_keyring (No module named mercurial_keyring): trying mercurial_keyring could not import hgext.hggit (No module named hggit): trying hgext3rd.hggit could not import hgext3rd.hggit (No module named hggit): trying hggit tip (This get worse if --traceback is used). To work around this, we move this extensions related debug message behind a new flag 'devel.debug.extensions' and restore the previous output. I'm not fully happy about using the 'devel' section for a flag that can be used by legitimate users to debug extensions issues. However, it fits well next to other `devel.devel.*` options and is mostly used by extensions author anyway. We might move it to another, more appropriate section in the future (using alias).
