test-static-http: partially adapt for Windows

test-bad-pull: partially adjust for Windows On a English Windows 7, the testcase fails with $ hg clone http://localhost:$HGPORT/ copy abort: error: No connection could be made because the target machine actively refused it Since the error message on non-English Windows installs are most likely different, we have to glob the entire error message away for Windows.

tests: consistently use printenv.py the same MSYS/Windows-compatible way This will remove some reasons some tests are disabled on Windows.

tests: prepare get-with-headers.py for MSYS get-with-headers.py took the http GET parameter as a command line parameter that had to start with '/'. MSYS on windows will mangle such paths. Instead of applying a workaround everywhere (such as an extra '/') we let get-with-headers.py add the mandatory '/'. That is consistent with the url path handling in the Mercurial url class. A few tests sent 'GET ?cmd=...' which is invalid. They will now send 'GET /?cmd=...'. This will not enable any tests for being run on windows - only remove one reason they were disabled.

tests: hghave outer-repo should be true even if a bad repo is found Only the abort message 'no repository found' is a reliable indication that there is no outer repo.

tests: add missing no-outer-repo requirements Outer repos (if any) will now never be touched by the tests. But it is better to run without any repos around the tmp directory.

tests: convert some 'hghave no-outer-repo' to #if In some places we instead use 'hg init' to create a well-known outer repo without any special extensions or other config settings.

strip: incrementally update the branchheads cache after a strip This function augments strip to incrementally update the branchheads cache rather than recompute it from scratch. This speeds up the performance of strip and rebase on repos with long history. The performance optimization only happens if the revisions stripped are all on the same branch and the parents of the stripped revisions are also on that same branch. This adds a few test cases, particularly one that reproduces the extra heads that mpm observed.
