dfe2bde88d Dirty cache of HEAD commit after an amend/range reload
Summary:
Introducing `--head` caused us to run `git diff base..head` explicitly.

However, we can now hit this workflow:

  - We resolve `HEAD` as commit `aaaa1`.
  - This is cached.
  - We notice dirty working copy changes and prompt the user to amend them to HEAD.
  - The user accepts the amend.
  - We amend, creating commit `bbbb2`.
  - We dirty the commit range and reload the working copy. This //does not// dirty the cache of HEAD.
  - We run `git diff`, but it uses the old cached HEAD: `git diff base..aaaa1`.
  - This works fine (`aaaa1` still exists, it's just not on any branch) but produces the wrong diff (without amended changes).

To resolve this, implement the "dirty the cache when the range reloads" hook.

Also never try to amend if the user provides `--head`.

Test Plan:
Ran `arc diff --only --trace` in a working copy with a new commit and some uncommitted changes.

  - Prior to this change, saw a `git diff base..aaaa1` command and the wrong diff.
  - After this change, saw a `git diff base..bbbb2` command and the correct diff.

6b192f3178 --range support for git
Summary:
This adds support for passing range of commits for arc diff. This is useful when you want to submit code reviews for past commits without mucking around with the working copy.

This will probably require changes :)

Test Plan: Tested locally, but totally need to add tests for this

b189b594d2 Present case of class and interface names.
Summary: Currently, class and interface names are converted to lowercase when comparing minimum and maximum versions. This is necessary in order to compare with the data from `php_compat_info.json` but causes the lint message to be slightly misleading.

02e3905cf5 Don't lint symlinks by default.
Summary: Fixes T5300. Currently, if a dead symbolic link is linted, all kinds of errors will be thrown by most linters because they will try to read the (non-existent) file contents. Instead, let's not lint symbolic links by default. In the case that the target of a symbolic link is inside the working copy, then it should be being linted anyway.

Test Plan: Created a symbolic link and verified that it wasn't linted (by any linter other than the `ArcanistFilenameLinter`).

833ce45155 Lint the ArcanistSpellingDefaultData class.
Summary:
Currently, the `ArcanistSpellingDefaultData` is marked with a `@nolint` annotation. This means that it doesn't get linted by any linters. Really, the intention here was to make sure that this file isn't linted by the `ArcanistSpellingLinter` linter.

Now that the `.arclint` file is more mature, we can easily just exclude this file from being linted //only// by the spelling linter, whilst allowing other linters to run.

Test Plan: Ran `arc lint`.

c999f3e6b5 Fix XHPAST to detect use of undeclared variables in catch
Summary:
Currently, when code has a block like:

  } catch (Exception $ex) {

...we attempt to mark "$ex" as declared. However, we incorrectly mark every variable used anywhere in the block as declared. This means we'll never raise this warning in a `catch` block.

Instead //only// mark the caught exception as declared.

Test Plan: Added a failing unit test and made it pass.

104219dd62 Improve 'arc get-config', 'arc set-config' and show more config info with --trace
Summary:
Fixes T4952. Several issues:

  - You review configuration values with `arc set-config --show`. This makes no sense and never has, I think it just predated `arc get-config` or was easier or something.
    - Instead, review values with `arc get-config` and review details with `arc get-config --verbose`.
  - Show better and more detailed information about all config sources.
  - Establish and show default values from a new "default" source.
  - With `--trace` include more information about attempts to read configuration files.

Test Plan:
Ran `arc get-config --trace --verbose` in various working directories and received sensible-looking output.
