The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
zval_dtor() doesn't make a lot of sense in PHP-7.* and it's used incorrectly in some places.
Its occurances should be replaced by zval_ptr_dtor() or zval_ptr_dtor_nogc(), or even more specialized destructors.
vs(tr)pprintf is now implemented in Zend on top of
printf_to_smart_str(int), which is provided as a utility function.
This allows us to efficiently printf to the end of a smart string.
It's annoying that in Zend you have to use zend_strpprintf instead
of strpprintf, while in PHP you have to use strpprintf instead of
zend_strpprintf.
Make zend_s(tr)pprintf always available and keep s(tr)pprintf as
macro aliases.
spprintf now always creates a buffer and strpprintf always returns
a zend_string. Previously, if the result of the format happened to
be empty, the spprintf buffer would be set to NULL and strpprintf
would return NULL.
So we can use it there as well...
For now I've retained the zend_smart_str_public.h header, though
it would probably be better to just move that one struct into
zend_types.h.

#This fix (for g/G/k/H modes) is done at a different level than that for the
#modes e/E/f/F, at a bit higher level and therefore with less coverage. I
#chose this because it addresses the problem where it is -- the calling function
#that passes a buffer too small to php_gcvt.
