Support rendering arbitrary sections in the middle of a Harbormaster build log so links to line 3500 work

Browse source 
Summary:
Depends on D19162. Ref T13088. When a user links to `$1234`, we need to render a default view of the log with a piece at the head, a piece at the end, and a piece in the middle.

We also need to figure out the offset for line 1234, or multiple offsets for "1234-2345".

Since the logic views/reads mostly anticipated this it isn't too much of a mess, although there are a couple of bugs this exposes with view specifications that use combinations of parameters which were previously impossible.

Test Plan: Viewed a large log with no line marker. Viewed `$1`. Viewed `$end`. Viewed `$35-40`, etc. Expanded context around logs.
