First step in two-part process to rename directories to kallithea.
This first step is to change all references in the files where they refer
to the old directory name.

Imported some of the GPLv3'd changes from RhodeCode v2.2.5.

This imports changes between changesets 21af6c4eab3d and 6177597791c2 in
RhodeCode's original repository, including only changes to Python files and HTML.

RhodeCode clearly licensed its changes to these files under GPLv3
in their /LICENSE file, which states the following:
The Python code and integrated HTML are licensed under the GPLv3 license.

(See:
https://code.rhodecode.com/rhodecode/files/v2.2.5/LICENSE
or

for an online copy of that LICENSE file)

Conservancy reviewed these changes and confirmed that they can be licensed as
a whole to the Kallithea project under GPLv3-only.

While some of the contents committed herein are clearly licensed
GPLv3-or-later, on the whole we must assume the are GPLv3-only, since the
statement above from RhodeCode indicates that they intend GPLv3-only as their
license, per GPLv3§14 and other relevant sections of GPLv3.

fixes issue #860.

IMC web commits poisoned caches when they failed. We now
always invalidate caches so objects are refreshed and will be accessible.

accept that repos are read-only - very convenient for testing.

Users are prompt to confirm they want to use read only paths.
org author: Mads Kiilerich

fixes issues #849 IMC failed for non-ascii files

- added set of regression tests into vcs lib

Fake post-push actions when doing git fetch. It's still want show
what revisions we fetched but at least we trigger the action

Do read only checks on attach as fork of repo list.
We shouldn't leak repo names here to which we don't
have access

Implemented simple gist functionality ref #530.

- creation of public/private gists with given lifetime
- rhodecode-gist CLI for quick gist creation

fixed issue with web-editor that didn't preserve executable bit
after editing files

invalidation: merge .invalidate and .set_valid as .test_and_set_valid

This simplifies the internal API and avoids leaking CacheInvalidation instances
and cache keys.

api: don't report invalidated cache_keys after invalidating a repo

The keys are an implementation detail and is never relevant outside RhodeCode
internals and should not be leaked.

- Manage User’s Groups: create, delete, rename, add/remove users inside.
by user group admin.
In this case, a user's group can be owned by several people thru an owner user's group.

Some refactoring of naming, permission handling logic.
- remove some code duplicity as well as inconsistent naming

Switched handling of RhodeCode extra params in consistent way
- use only os.environ for both hg and git
- hacking ui objects was bad
- os.environ allows easier to call rhodecode hooks externally

iterate over repos groups for bool() calls to actually work on it.
fixes some issues with correctly displaying if there are no groups you have permission to.

reposcann should skip directories with starting with '.'
some code cleanup, moved all skipping to get_repos function

Return a list of invlidated keys on mark_for_invalidation func
- log.debug list of invalidated keys

some code cleanup, moved all skipping to get_repos function

Group management delegation:
this allows users to become an admin of groups
a group admin can manage a group, change it's name
or permissions. A group admin can create child group
only within a group he is an admin off.

Top-level group can be only created by super admins

don't recurse into '.hg' of removed repositories

Walking through the content of a '.hg' that has been renamed to 'rm__.hg' on
startup can take a lot of time.

Cleaned the way cache keys are invalidated
should fix issue #504 RhodeCode is showing different
versions of README on different summary page loads

Implemented basic locking functionality.

- Reimplemented how githooks behave
- emaulate pre-receive hook
- install missing git hooks if they aren't already in repo

Bumped mercurial version to 2.3
- fixed issues with compare of two remote repos at particular revisions
- added tests for cases when mercurial update broke code and tests didn't catch this
- removed obsolete EmptyChangeset from the rhodecode code

Fixed issue #501 error on setting set_as_fork to same repo
- also fixed html fill select set
- wrote set of tests for that option

Created install_git_hook more verbose version of previos code.
- allows autoupdating hooks in later releases

Fixed calls to Session in db model
- added inject_ui method that should be later used for all injections of extra parameters into ui
- fixed naming conflict of `comments` functions and relationship that had the same name

Initial version of landing revisions ref #483
- fixed relevant tests for creation of repo
- added some tests for git

- pull request generates overview based on it's params
- added page to show all pull-requests for a repository
- db schema changes to support comments and inline comments for pull-requests

Implemented cache-map on main page to save executing select
statements that checks if cache should be invalidated.
It reduces number of executed queries from N which is number of
repos to 1 which is needed to fetch all keys from database.
On pages with large number of repos this could reduce load time by half

Implemented pull command for remote repos for git
- added mimic ui objects into GitRepos to better handle hooks logic

various fixes for git and mercurial with InMemoryCommit backend and non-ascii files
- hg use tolocal for unicode objects
- git use core.quotepath=false for commands

- #347 when running multiple RhodeCode instances, properly invalidates cache
for all registered servers
- server start also clears all cache keys now

utils/conf
- created temporary utils2
- made config.conf for storing some configurations
- fixed some dependency import problems
- code cleanup
- rc-extensions now properly work for celery

fixed issues with removed repos was accidentally added as groups, after
full rescan of paths

#227 Initial version of repository groups permissions system
- implemented none/read/write/admin permissions for groups
- wrote more tests for permissions, and new permissions groups
- a lot of code garden, splitted logic into proper models
- permissions on groups doesn't propagate yet to repositories
- deprecated some methods on api for managing permissions on
repositories for users, and users groups

implements #330 api method for listing nodes at particular revision
- improved filtering by files in file list

moved soon-to-be-deleted code from vcs to rhodecode
- diff lib
- annotate highlighter

Summary page downloads limited to zip.
- changing url can download also other formats
- just zip is enough for most cases
- looks cleaner

- fixes celery sqlalchemy session issues for async forking
- summary page css fixes
- speed optimizations

#235 forking page repo group selection
- group is selected as parent repo
- refactoring of session behavior to get more atomic operations in models

Cached readme generation
- cleaned up cache system

API added checks for a valid repository on pull command
Added pre-check if repository have a remote_uri defines before pulling
bugfix with no default arguments on api function
added traceback when unhandled exception occurs on API

Fixes issue #201
Fixed bug when repository was deleted on filesystem, and not from rhodecode
