Don't overwrite unwind exception

When killing a coroutine by throwing an unwind exit into it during
an I/O operation, the I/O failure may result in an exception being
thrown, which will replace the unwind exit exception and the
coroutine will ultimately not exit. This patch avoids this by
ignoring the newly thrown exception and keeping the unwind exit
exception.

Closes GH-7459.

Fix bug #81303 improve match errors

Add additional double to string APIs

zend_double_to_str() converts a double to string in the way that
(string) would (using %.*H using precision).

smart_str_append_double() provides some more fine control over
the precision, and whether a zero fraction should be appeneded
for whole numbers.

A caveat here is that raw calls to zend_gcvt and going through
s*printf has slightly different behavior for the degenarate
precision=0 case. zend_gcvt will add a dummy E+0 in that case,
while s*printf convert this to precision=1 and will not. I'm
going with the s*printf behavior here, which is more common,
but does result in a minor change to the precision.phpt test.

Direct creation of GracefulExit allows the the special exception object to be transfered and thrown into a destroyed fiber using the same path as any other exception thrown into a fiber instead of needing to check for a flag.

Convert exception during inheritance to fatal error

Now that inheritance can throw deprecations again, these may be

we need to convert the exception to a fatal error, as inheritance
cannot safely throw in the general case.

Use common formatting for backtraces (#6977)

This makes debug_print_backtrace() use the same formatting as exception
backtraces. The only difference is that the final #{main} is omitted,
because it wouldn't make sense for limited backtraces, and wasn't there
previously either.

Make convert_to_*_ex simple aliases of convert_to_*

Historically, the _ex variants separated the zval first, if a
conversion was necessary. This distinction no longer makes sense
since PHP 7.

The only difference that was still left is that _ex checked whether
the type is the same first, but the usage of these macros did not
actually distinguish on whether such an inlined check is valuable
or not in a given context.

Also drop the unused convert_to_explicit_type macros.
