Summary:
Add linting capability for detecting files which contain
syntax introduced by unresolved merge conflicts. The detection is
file-type-agnostic (the only requirement is that the file is a text
file).
Test Plan:
Tested in three ways.
The first way is to add all three forms of syntax to a file to
indicate a merge conflict. HPHP will pick this up as a syntax error
before this linter reaches it.
The second way is to add the syntax in a comment. In that case, this
linter will show three warnings. For example:
$ arc lint ArcanistMergeConflictLinter.php
>>> Lint for arcanist/src/lint/linter/ArcanistMergeConflictLinter.php:
Warning (MERGECONFLICT1) Unresolved merge conflict
This syntax indicates there is still an unresolved merge conflict.
20
21 foreach ($lines as $lineno => $line) {
22 /*
>>> 23 >>>>>>>
24
25 =======
Warning (MERGECONFLICT1) Unresolved merge conflict
This syntax indicates there is still an unresolved merge conflict.
22 /*
23 >>>>>>>
24
>>> 25 =======
26
27 <<<<<<<
Warning (MERGECONFLICT1) Unresolved merge conflict
This syntax indicates there is still an unresolved merge conflict.
24
25 =======
26
>>> 27 <<<<<<<
28
29 */
The last test was to test on various different file types, including
JavaScript, PHP, an animated GIF, a PNG, and a Bash file to make sure
the file type detection worked. Each of the aforementioned tests
passed.

Summary:
Some errors (duplicate declaration, invalid number of arguments) have more related places.
We need to notify user if he changes any related place.
This could be currently achieved by triggering errors instead of warnings or by including both files in the range (impossible if the locations are in different files) or by issuing multiple errors.
All options are too aggressive.
Test Plan: Issued error on unmodified line with other location on modified line.
