Changes in Devel::NYTProf 6.08 - DATE TO COME

B<There should be no observable differences in the performance of Devel-NYTProf
from that of the previous release.>  This release is maintenance-focused and
changes mainly concern improvements in test coverage, elimination of
build-time warnings and correction of small errors detected by end-users.

=head3 Substantive

Corrected 1 error in F<Makefile.PL>
(L<https://github.com/timbunce/devel-nytprof/pull/158>; thanks to Kent \ 
Fredric).

Corrected other errors in F<NYTProf.xs> and F<ppport.h> at \ 
suggestion of Reini Urban
in earlier pull request.

Two subroutines in F<Devel::NYTProf::Data> -- \ 
C<packages_at_depth_subinfo()>
and C<package_fids()> -- which were not used anywhere in the codebase or test
suite were removed and placed in F<devstuff/superseded.pm>.  One function --
C<get_str_id()> defined in F<NYTProf.xs> but never used in the \ 
codebase was
similarly removed and placed in F<devstuff/superseded.xs>.  Anyone who was
using these functions may file a pull request to have them restored to the
codebase.

In C<Devel::NYTProf::Data::strip_prefix_from_paths()>, a branch concerned with
the possibility that an argument was a hash was not exercised anywhere in the
codebase or the test suite and was simply commented out.  Anyone who was using
this functionality may file a pull request to have it restored to the
codebase.

Eliminated all build-time warnings being generated during F<make> on testing
platforms Linux, FreeBSD, OpenBSD, Windows.

=head3 Test Suite

Improved coverage provided by test suite to each of the following files:

    lib/Devel/NYTProf/Data.pm
    lib/Devel/NYTProf/FileInfo.pm
    lib/Devel/NYTProf/Reader.pm
    lib/Devel/NYTProf/SubInfo.pm
    lib/Devel/NYTProf/Util.pm

This was accomplished mainly by adding 4 new test files:

    t/11-reader.t
    t/12-data.t
    t/13-fileinfo.t
    t/14-subinfo.t

... and their corresponding data files.  In addition, there were substantial
additions to F<t/30-util.t>.

Coverage was evaluated with C<trace_level> unset and C<trace_level> 5.

=head3 Housekeeping

Updated Travis and AppVeyor configuration files.

Updated F<MANIFEST> and F<MANIFEST.SKIP> so that F<make \ 
manifest> works as intended.

Moved the following 6 test files from F<t/> to F<xt/>:

    t/68-hashline.t
    t/71-moose.t
    t/72-autodie.t
    t/90-pod.t
    t/91-pod_coverage.t
    t/92-file_port.t

Reason:  They either (a) had been previously described as insufficiently
developed and were being skipped; or (b) are of concern only to NYTProf
developers.  Hence, a failure in any of them should not preclude installation
and use of Devel::NYTProf.

Added a F<make test_short> target to F<Makefile.PL> and \ 
environmental variable
C<NYTPROF_TEST_SHORT>.  These will enable NYTProf developers to cut testing
time without significant loss in accuracy
(L<https://github.com/timbunce/devel-nytprof/pull/155>).

Corrected one date error in 6.07 release
(L<https://github.com/timbunce/devel-nytprof/issues/152>; thanks to \ 
@shawnlaffan).

Applied several commits either cherry-picked from, or initiated by Reini Urban
in an older pull request.

=head2 Changes in Devel::NYTProf 6.07 - 6th April 2021
