tests: cleanup of svn url handling The subversion tests used different tricks to create properly encoded URLs, partly due to partial support for different ways of running the tests on windows. Now we only need/support one way of running the tests on windows. Windows URLs should look like 'file:///c:/foo%20bar' and on Unix platforms like 'file:///tmp/baz'. 'pwd' in the test framework will on Windows emit paths like 'c:/foo bar'. Explicit handling of backslashes in paths is thus no longer needed and is removed. Paths on windows do however need an extra '/' compared to other platforms. This change makes test-subrepo-svn.t pass on windows with msys. Other tests might need more work.

test-subrepo-svn.t: partially adapt for Windows hg forget 'notafile*' is changed to use a name that is valid on Windows so we still get the same error ... but the error message is disabled because it varies with the Windows version.

convert: ignore svn:executable for subversion targets without exec bit support Calling propset/propdel with subversion 1.6 on FAT gave abort: svn exited with status 256 and made test-convert-hg-svn.t and test-convert-svn-sink.t fail. 1.7 worked. This is a rework of fdee5d614fcc but ignores the executable bit when it isn't supported instead of using an approximation.

rebase: improve error message on improper phases The previous error message had two issues: The first issue was that it wasn't, in fact, an error but a warning, even though it described a fatal error condition preventing the successful completion of the command. The second was that it didn't mention the immutable changesets, leaving the user guessing at the true cause of the error. The main downside to this change is that we now get an 'abort: can't abort...' message which technically contradicts itself. In this case, I blame that on the two uses we have for the word; if it weren't for backwards compatibility, we could make util.Abort print out 'error: <whatever>'.

subrepo: support Git being named "git.cmd" on Windows (issue3173) Popen does not consider "foo.cmd" equivalent to "foo" on Windows. Unfortunately, the default MSYS Git installation installs only "git.cmd" into the path by default. This patch probes for both possible names on Windows.

subrepo: warn user if Git is not version 1.6.0 or higher
