Querying all counts for the different search results in the same request
led to timeouts, so we now only calculate the count for the *current*
search results, and request the others in separate asynchronous calls.
Remove project from NotesFinder constructor
Add project parameter to specs
Also look for methods in private scope
Fix specs to match new NotesFinder constructor
Removed the conditions added to
Project.with_feature_available_for_user, and moved to the
IssuableFinder. Now, we ensure that, in the projects retrieved
in the Finder, the user has enough access for the feature.
* removed 100 limit on file search results because we
load all results anyway
* expensive processing (parsing match content, utf encoding)
is done only for selected page in paginated output
Search query is especially slow if a user searches a generic string
which matches many records, in such case search can take tens of
seconds or time out. To speed up the search query, we search only for
first 1000 records, if there is >1000 matching records we just display
"1000+" instead of precise total count supposing that with such amount
the exact count is not so important for the user.
Because for issues even limited search was not fast enough, 2-phase
approach is used for issues: first we use simpler/faster query to get
all public issues, if this exceeds the limit, we just return the limit.
If the amount of matching results is lower than limit, we re-run more
complex search query (which includes also confidential issues).
Re-running the complex query should be fast enough in such case because the
amount of matching issues is lower than limit.
Because exact total_count is now limited, this patch also switches to
to "prev/next" pagination.

A file containing /:\d+:/ in its contents would break the search results if
those contents were part of the results, because we were splitting on colons,
which can't work with untrusted input.
Changing to use the null byte as a separator is much safer.
