Matt Giuca 2cd3c14ef7 git_hyper_blame: Fix wrong line number on lines changed many times.
This could, in extreme cases, result in a crash due to the wrong line
number being out of bounds of the file line count.

mgiuca@chromium.org 63906bac40 git-hyper-blame: Fix pagination (uses less if on a TTY).
This was broken in r299682 (adding setup_color). git_hyper_blame now
initializes setup_color.

mgiuca@chromium.org cd0a1cf362 git hyper-blame: Added automatically ignoring revs from a file.
Added --ignore-file argument, so you can specify ignored commits in a
file rather than as raw command-line arguments. Also, automatically
searches for a file called .git-blame-ignore-revs, which is
automatically used as an ignore list by default.

Also, specifying an unknown revision (either on the command line or in a
file) now generates a warning, not an error.

Notes on some decisions:
- The file is called .git-blame-ignore-revs (not mentioning hyper-blame)
  because we may use the same list in tools other than hyper-blame in
  the future.
- We look at the *currently checked out* version of
  .git-blame-ignore-revs (not the version at the specified revision) for
  consistency with .git-ignore. Because we only expect revisions to be
  added (not deleted), it should be fine to use an ignore list from a
  newer version than the revision being blamed.
- We considered using git notes for the ignore list so that you could
  add a revision to the ignore list without needing a follow-up CL.
  However, there are some problems with this approach. git notes is not
  automatically synced with git clone/pull. Also the Chromium infra
  tools (Reitveld, CQ) are not set up to allow modification of git
  notes, nor are changes to git notes subject to OWNERS checks. Using a
  regular file ensures all users synced to a particular revision are
  using the same ignore list.

mgiuca@chromium.org 01d2cde990 git hyper-blame: Added approx. line number translation.
Previously, when a commit was skipped, it would be blamed on the line
number the line had *after* the skipped commit. This could mean a
totally unrelated commit gets blamed. Now, a heuristic analyses the diff
of the skipped commit to discover approximately what line number the
line had *before* the skipped commit, so it can hopefully be blamed on
the right commit.

mgiuca@chromium.org 819375653b Added git hyper-blame, a tool that skips unwanted commits in git blame.
Currently, the script requires you to pass the unwanted commits on the
command line, but eventually, you could configure it with a file
(checked into the repo) that provides a fixed set of commits to always
skip (such as commits that do a huge amount of renaming and nothing
else).
