Show 'CONFLICT' indicator at command prompt
This patch adds functionality for bash/zsh to show "CONFLICT" on the
prompt in cases where there are unresolved conflicts. The feature is
only enabled after setting an environment variable.
The conflict state is determined by running git ls-files --unmerged. In
my testing, the performance was very good. It took around 0.01 seconds
to run git ls-files --unmerged regardless of the number of conflicts, or
their depth, even on very large projects (Linux kernel). However, if
anybody has any concerns with this, I'm open to other options.
Any tests that were impacted (with the conflict prompt feature enabled)
were duplicated. The original test was left as-is (no changes, and
conflict prompt feature disabled). The new version of each test enables
the conflict prompt feature and confirms the prompt includes
"|CONFLICT".
------------------------------------------------------------------------
Changes since v1:
* This feature is now disabled by default.
* Created new tests for conflict state (instead of modifying existing
tests).

## Commit message ##
- git-prompt: show 'CONFLICT' indicator at command prompt
+ git-prompt: show presence of unresolved conflicts at command prompt
- When there are unresolved conflicts, show the word 'CONFLICT' on the
- command prompt. Similar to other state indicators, this provides
- information to the user about the current state of the repository.
+ If GIT_PS1_SHOWCONFLICTSTATE is set to "yes", show the word "CONFLICT"
+ on the command prompt when there are unresolved conflicts.
