a582931f42 Revert "Revert "Merge branch 'PHP-7.4'""
This reverts commit 28e650a, which reverted commit 046dcfb, which had
to be reverted due to phpdbg issues.  The culprit was that we did not
properly reset `zend_handler_table` to `NULL`, which is required for
SAPIs which may restart the engine after shutdown.

28e650abf8 Revert "Merge branch 'PHP-7.4'"
This reverts commit 046dcfb531, due to
segfaults on Travis.  This needs to be investigated.

4130fe437a Make MSVCRT memory leak checking usable for the test suite
While basic support for MSVCRT debugging has been added long
ago[1], the leak checking is not usable for the test suite, because we
are no longer calling `xmlCleanupParser()` on RSHUTDOWN of
ext/libxml[2], and therefore a few bogus leaks are reported whenever
ext/libxml is unloaded.

We therefore ignore memory leaks for this case.  We introduce
`ZEND_IGNORE_LEAKS_BEGIN()` and `ZEND_IGNORE_LEAKS_END()` to keep
those ignores better readable, and also because these *might* be
useful for other leak checkers as well.

We also explicitly free the `zend_handlers_table` and the `p5s` to
avoid spurious leak reports.

1ad08256f3 Sync leading and final newlines in source code files
This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.

According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.

C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."

Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

49cf7c5d12 Don't propogate "fake" EX(called_scope) and EX(This) into each internal function.
They need quite seldom and it's cheaper to get them from corresponfing upper stack frame.

70f83f35d0 . The VM stacks for passing function arguments and syntaticaly nested calls were merged into a single stack. The stack size needed for op_array execution is calculated at compile time and preallocated at once. As result all the stack push operatins don't require checks for stack overflow any more.
. Generators implementation was improved using the new VM stack. Now it's a bit more clear and faster.
