status: add a flag to terse the output (issue4119)

This adds an experimental flag -t/--terse which will terse the output. The terse flag
will respect other flags which filters the output. The flag takes a string
whose value can be a subsequence of "marduic" (the order does not matter here.)

Ignored files are not considered while tersing unless -i flag is passed or 'i'
is there is the terse flag value.

The flag is experimental for testing as there may be cases which will produce
strange results with the flag. We can set the terse on by default by simply
passing 'u' to the cmdutil.tersestatus().

This patch also adds a test file with tests covering the new feature.

+      The -t/--terse option abbreviates the output by showing directory name
+      if all the files in it share the same status. The option expects a value
+      which can be a string formed by using 'm', 'a', 'r', 'd', 'u', 'i', 'c'
+      where, 'm' stands for 'modified', 'a' for 'added', 'r' for 'removed',
+      'd' for 'deleted', 'u' for 'unknown', 'i' for 'ignored' and 'c' for clean.

+      It terses the output of only those status which are passed. The ignored
+      files are not considered while tersing until 'i' is there in --terse value
+      or the --ignored option is used.
