patch
Add "yes" argument for the --modify-fds option.
Use --modify-fds=yes to restrict the option from affecting
the 0/1/2 file descriptors as they're often used for
stdin/tdout/stderr redirection.
The new possibility is named "yes" because "yes" is used
as the default in general. The default behaviour of the --modify-fds
option is then such, that highest available file descriptor is returned
execept when the lowest stdin/stdout/stderr (0, 1, 2) are available.
For example, if we want to redirect stdout to stderr by closing stdout
(file descriptor 1) and then calling dup (), file descriptor 1 will be
returned and not the highest number available. This is because the
following is a common pattern to redirect stdout to stderr:
close (1);
/* stdout becomes stderr */
ret = dup (2);
Add none/tests/track_yes.vgtest and none/tests/track_high.vgtest
tests to test --modify-fds=yes/high behave as expected.
