Case insensitivity support for .gitignore via core.ignorecase

Browse Source 
This is especially beneficial when using Windows and Perforce and the
git-p4 bridge. Internally, Perforce preserves a given file's full path
including its case at the time it was added to the Perforce repository.
When syncing a file down via Perforce, missing directories are created,
if necessary, using the case as stored with the filename. Unfortunately,
two files in the same directory can have differing cases for their
respective paths, such as /diRa/file1.c and /DirA/file2.c. Depending on
sync order, DirA/ may get created instead of diRa/.

It is possible to handle directory names in a case insensitive manner
without this patch, but it is highly inconvenient, requiring each
character to be specified like so: [Bb][Uu][Ii][Ll][Dd]. With this patch, the
gitignore exclusions honor the core.ignorecase=true configuration
setting and make the process less error prone. The above is specified
like so: Build
