identify: document -r. explicitly how to disable wdir scanning (issue5622)

diff: disable diff.noprefix option for diffstat (issue5759) We could use patch.diffhunks() instead of patch.diff() to get filenames without parsing patch content, but that isn't always possible because we sometimes feed raw patch data to patch.diffstat().

hgweb: disable diff.noprefix option for diffstat Copied from cf1e15f91c90.

debugssl: convert port number to int (issue5757) It doesn't use util.getport(), which may resolve service name to port number.

histedit: preserve active branch while histediting The branch information was properly preserved in the changeset, but the "active" branch of the working copy could be lost (the branch of the base being used). Histedit used to behave properly in this regard but the case was not tested and regressed 4 years ago in ab2362e1672e.

templater: fix "one arguments"

tests: write and use a custom helper script to avoid find's -printf -printf on find is a GNU-ism and will be banned in an upcoming check-code change. Differential Revision: https://phab.mercurial-scm.org/D1597

convert: restore the ability to use bzr < 2.6.0 (issue5733) This effectively conditionalizes a234b32b744a. Some Linux distributions (like CentOS 7) use really old versions, and the change referenced was causing exceptions to be thrown. Even though the deprecation warning says 'since 2.5.0', it wasn't marked as such in 2.5.1, but is by 2.6.0. This was tested with 2.4.2 and 2.6.0 with PYTHONWARNINGS=::DeprecationWarning, and both paths were exercized.

merge: check created file dirs for path conflicts only once (issue5716) In large repositories, updates involving the creation of many files check the same directories repeatedly in the wctx manifest. Move these checks out to a separate loop to avoid repeated checks hitting the manifest. Differential Revision: https://phab.mercurial-scm.org/D1226

merge: cache unknown dir checks (issue5716) As mentioned in D1222, the recent pathconflicts change regresses update performance in large repositories when many files are being updated. To mitigate this, we introduce two caches of directories that have already found to be either: - unknown directories, but which are not aliased by files and so don't need to be checked if they are files again; and - missing directores, which cannot cause path conflicts, and cannot contain a file that causes a path conflict. When checking the paths of a file, testing against this caches means we can skip tests that involve touching the filesystem. Differential Revision: https://phab.mercurial-scm.org/D1224

dispatch: add HGPLAIN=+strictflags to restrict early parsing of global options If this feature is enabled, early options are parsed using the global options table. As the parser stops processing options when non/unknown option is encountered, it won't mistakenly take an option value as a new early option. Still "--" can be injected to terminate the parsing (e.g. "hg -R -- log"), I think it's unlikely to lead to an RCE. To minimize a risk of this change, new fancyopts.earlygetopt() path is enabled only when +strictflags is set. Also the strict parser doesn't support '--repo', a short for '--repository' yet. This limitation will be removed later. As this feature is backward incompatible, I decided to add a new opt-in mechanism to HGPLAIN. I'm not pretty sure if this is the right choice, but I'm thinking of adding +feature/-feature syntax to HGPLAIN. Alternatively, we could add a new environment variable. Any bikeshedding is welcome. Note that HGPLAIN=+strictflags doesn't work correctly in chg session since command arguments are pre-processed in C. This wouldn't be easily fixed.

fancyopts: add early-options parser compatible with getopt() The next patch will add a flag for strict parsing of early options, where we'll have to parse all early options at once instead of processing them one-by-one by dispatch._earlygetopt(). That's why I decided to hook fancyopts(). All dispatch._early*opt() functions is planned to be replaced with this function. But in this stable series, only the strict mode will be handled by fancyopts.earlygetopt().
