* lisp/emacs-lisp/testcover.el: Rewrite the internals of Testcover
to analyze instrumented code instead of reinstrumenting it. Use new
hooks in Edebug to collect code coverage information at runtime
using Edebug's instrumentation.
Includes fixes for: (bug#11307) (bug#24509) (bug#24688) (bug#24743)
(bug#25316) (bug#25326).
(testcover-compose-functions): Remove mapcar.
(testcover-start, testcover-this-defun): Analyze code instead of
reinstrumenting it. Set edebug-behavior for each definition.
(testcover--read, testcover-1value, testcover-reinstrument)
(testcover-reinstrument-list, testcover-reinstrument-compose):
Deleted.
(testcover-after-instrumentation, testcover-init-definition)
(testcover-before): New functions.
(testcover-enter): Change call signature to match edebug-enter.
(testcover-after, testcover-mark): Add handling of 'maybe and
'noreturn.
(testcover-analyze-coverage, testcover-analyze-coverage-progn)
(testcover-analyze-coverage-edebug-after)
(testcover-analyze-coverage-wrapped-form)
(testcover-analyze-coverage-wrapped-application)
(testcover-analyze-coverage-compose)
(testcover-analyze-coverage-backquote)
(testcover-analyze-coverage-backquote-form)
(testcover-coverage-combine): New functions to analyze instrumented
code.
* lisp/emacs-lisp/gv.el: Modify edebug-after's gv-expander to
instrument in the setter as well as the getter.
* test/lisp/emacs-lisp/testcover-tests.el
(testcover-tests-run-test-case): Use `edebug-default-enter'
instead of `edebug-enter' to detect Edebug invocation
during tests.
* test/lisp/emacs-lisp/testcover-resources/testcases.el

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
