[PATCH v3 3/8] git-p4: match branches case insensitively if configured

From

<6eaad2582c14961ec682d299267b279ce16906ef.1554141338.git.amazo@checkvideo.com>

git-p4 knows how to handle case insensitivity in file paths if core.ignorecase is set. However, when determining a branch for a file, it still does a case-sensitive prefix match. This may result in some file changes to be lost on import.

For example, given the following commits
 1. add //depot/main/file1
 2. add //depot/DirA/file2
 3. add //depot/dira/file3
 4. add //depot/DirA/file4
and "branchList = main:DirA" branch mapping,
commit 3 will be lost.

So, do branch search case insensitively if running with core.ignorecase set. Teach splitFilesIntoBranches() to use the p4PathStartsWith() function for path prefix matches instead of always case-sensitive match.
