lib: drop is_hg and is_git

It is just as simple to be explicit.

py3: remove safe_unicode in places where it no longer is needed because all strings (except bytes) already *are* unicode strings

(The remaining safe_unicode calls are still needed and can't just be removed,
generally because we in these cases still have to convert from bytes to unicode
strings.)

vcs: introduce 'branches' attribute on changesets, making it possible for Git to show multiple branches for a changeset

Mercurial changesets will always have have exactly one branch (which might be
"default"). The VCS data model was the same.

Git allows for a changeset to have 0 or more branches ... and possibly one of
them as active. The right data model is thus to have an enumerable of branches.

We thus add a 'branches' attribute and use it where applicable.

The existing 'branch' attribute used some heuristics to decide which branch use
as "the" branch ... and in some places code (and tests) rely on that. We thus
keep that old method, knowing that some of its uses probably should move to
'branches'.

The code for retrieving Git branches is based on work by Dominik Ruf.

less: use .label and .label-* style instead of custom .*tag

This reduces the code and makes it more consistent.

Visualy this results in bold texts (which in case of small fonts is easier to read)
and a bit more padding left and right.

For a proper spacing, this requires to remove whitespaces before and after
the texts inside the labels.

Since the name changed from tag to label, also rename the variables and functions.

style: remove whitespace after icons

Where the additional spacing is needed, we already have a padding-right, so
these spaces are unnecessary. But more importantly they cause trouble if
text-decoration is used (i.e. underline on hover).

templates: change .node elements to <span>

This way we don't need to make them 'float: left'

templates: remove redundant pull-left and pull-right for changeset progress bars

"float: left" and "float: right" for these elements are already set in
kallithea-diff.less.

Aligns it with compare_diff.html which already didn't use "pull" on "node" and
"changes".

less: remove unnecessary .cur_cs

The class is only used once on a h6, which already is bold and has top and
bottom 10px margin. The 2px margin left and right are not really helpful.

style: rely on css to truncate author name in tables instead of truncating to fixed length

Dynamic truncation allows us in the future to use different length on different
screen sizes.

changeset range: move gravatar in front of revision link

In the past this was done by setting float:left on the gravatar.
This got lost during the partial bootstrap changes.
But the html layout should try to reflect the same order as the visual
representation. So this now does it in the html code.

style: rework review status icon handling

The styling had a reference to a '.container .changeset-status-ico' which might
collide with use of the Bootstrap 'container' class.

Investigation of that lead to complete removal of all changeset-status-ico and
changeset-status-container, plus related simplification of templates.

style: replace code-body etc with Bootstrap-ish panel and panel-heading, using panel-default for headers and tweak them grey

Based on work by Dominik Ruf.

style: use panel, panel-heading, panel-title, panel-body and settings

This imply lots of tweaking of header handling and panel spacing.

Not converted yet: codeblock code-header code-body.

Based on work by Dominik Ruf.

style: apply Bootstrap-compatible table.table class, now when the conflicting div.table styling is gone

Based on work by Dominik Ruf.

style: rename div.table to Bootstrap .panel-body

Based on work by Dominik Ruf.

style: introduce pull-left and pull-right in more places

Based on work by Dominik Ruf.

style: introduce h2 h3 h4 h5 for emphasis and drop some explicit styling

Based on work by Dominik Ruf.

style: introduce "clearfix" class where the Bootstrap migration will need it

Based on work by Dominik Ruf.

style: use Bootstrap compatible data-toggle="tooltip" markup

Based on work by Dominik Ruf and Andrew Shadura.

style: in preparation for bootstrap, replace kallithea title class with bootstrap compatible panel-heading

This is a subset of a bigger changeset. The subset was extracted by Mads Kiilerich, mostly by:

sed -i 's,<div class="title\>,<div class="panel-heading,g' `hg mani`
sed -i 's,\<div\.title\>,div.panel-heading,g' kallithea/public/css/style.css

style: in preparation for bootstrap, replace kallithea box with bootstrap compatible panel

This is a subset of a bigger changeset. The subset was extracted by Mads Kiilerich, mostly by:

sed -i \
-e 's,<div\(.*\) class="box",<div\1 class="panel panel-primary",g' \
`hg mani`

style: in preparation for bootstrap, use bootstrap compatible button class names

Give all buttons a styling (default, success, danger, warning) and rename the sizes to sm and xs.

This is a subset of a bigger changeset. The subset was extracted by Mads Kiilerich, mostly by:

sed -i \
-e 's,btn btn-small,btn btn-default btn-sm,g' \
-e 's,btn btn-mini,btn btn-default btn-xs,g' \
-e 's,btn-default btn-\(xs\|sm\) btn-\(success\|danger\|warning\),btn-\2 btn-\1,g' \
-e 's,class_="btn",class_="btn btn-default",g' \
`hg mani`

diff: correct handling of links to old filename in renames

There were links to the file at the parent revision ... but if the file had
been renamed, it used the wrong name.

diff: rework data structure used by diff_block.diff_block (used for changeset diffs)

Make it a pure reusable function that also can replace diff_block_simple.

Improve code clarity by using Python tuples for tuples.

fid and url_fid are just shuffled around - not cleaned up for now.

diff: minor cleanups

More consistency and preparing for later changes.

helpers: merge urlify_commit into urlify_text

More reuse - they are already almost doing the same.

test_urlify_test is updated to use the new repo_name parameter and urlify
hashes.

helpers: drop h.tooltip

h.tooltip did more magic in the past - now it just did a douple (or triple?)
escape of html.

c9cfaeb1cdfe removed most of the need for double escaping - and the places
where it is used, it must be 'tagged' with the safe-html-title class. Thus,
none of the remaining uses of h.tooltip are relevant (and might even be wrong);
normal automatic template escaping is just fine.

This is mostly:
sed -i 's,title="\${h.tooltip(\([^}]*\))}",title="${\1}",g' `hg mani`

spelling: fix title casing on translated template strings

Primarily texts.

templates: move site branding in page title to base template

Instead of repeating the same three lines in each and every template, move
it to the base template.

arrow_inout.png: replace icon-loop with icon-git-compare

A quick search revealed that some old css code was never used, so it was
removed.

remove unused javascript

.diff-menu-activate is removed in 929fc8d926d5

compare: introduce .cs_repo as the repo for .cs_changes - sometimes it is org, sometimes other

Influences pull request creation, display and compare.

Second step in two-part process to rename directories.
This is the actual directory rename.
