Fix GH-12675: MEMORY_LEAK in phpdbg_prompt.c
Have to use file_put_contents() instead of --FILE-- because we have to
actually load it using the exec command, *and* have to make multiple
files, and note that we can only load files relative from the current
directory, so we can't rely on files being in the sapi/phpdbg/tests
folder.

Closes GH-12680.

0f21cbc57c Fix GH-10715: phpdbg heap buffer overflow -- by misuse of the option "--run"
Fixes GH-10715

When a string starting with a NUL character is passed to
phpdbg_vprint(), the vasprintf() will return that 0 characters have been
printed. This causes msglen == 0. When phpdbg_process_print() is called
with a message of length 0, the -1 to check for '\n' will perform an out
of bounds read. Since nothing is printed anyway for msglen == 0, it
seems best to just skip the printing routine for this case.

Closes GH-10720.

Fix phpdbg segmentation fault in case of malformed input
If you were to enter "w $>" the function would crash with a segmentation
fault because last_index is still NULL at that point. Fix it by checking
for NULL and erroring out if it is.

3a44c78f14 Fix null pointer dereference of param
When the validation logic for param->type was added, the logic did not
account for the case where param could be NULL. The existing code did
take that into account as can be seen in the `if (param)` check below.
Furthermore, phpdbg_set_breakpoint_expression even calls
phpdbg_create_conditional_break with param == NULL.

Fix it by placing the validation logic inside a NULL check.

5f1311a92c Fix undefined behaviour in phpdbg_load_module_or_extension
If zend_register_module_ex were to return NULL, then module_entry will
be set to NULL, and the if's body will load module_entry->name. Since
module_entry is NULL, loading the name would cause a NULL pointer
dereference. However, since a NULL pointer dereference is undefined
behaviour, the compiler is free to remove the check.
Fix it by using *name instead of module_entry->name.

14f599ea7d Use zend_long for resource ID
Currently, resource IDs are limited to 32-bits. As resource IDs
are not reused, this means that resource ID overflow for
long-running processes is very possible.

This patch switches resource IDs to use zend_long instead, which
means that on 64-bit systems, 64-bit resource IDs will be used.
This makes resource ID overflow practically impossible.

The tradeoff is an 8 byte increase in zend_resource size.

Closes GH-7436.

054fad6d63 PHPDBG: fix bug parsing 3-word opcodes
PHPDBG won't parse opcodes correctly if they are more than two words
separated by underscores (as many opcodes, like ZEND_POST_INC, are).

Now opcodes that have more than one underscore (e.g. ZEND_POST_INC) are
parsed correctly.

47a2e5c785 Reference dynamic functions through dynamic_defs
Currently, dynamically declared functions and closures are inserted
into the function table under a runtime definition key, and then later
possibly renamed. When opcache is not used and a file containing a
closure is repeatedly included, this leads to a very large memory leak,
as the no longer needed closure declarations will never be freed
(https://bugs.php.net/bug.php?id=76982).

With this patch, dynamic functions are instead stored in a
dynamic_func_defs member on the op_array, which opcodes reference
by index. When the parent op_array is destroyed, the dynamic_func_defs
it contains are also destroyed (unless they are stilled used elsewhere,
e.g. because they have been bound, or are used by a live closure). This
resolves the fundamental part of the leak, though doesn't completely
fix it yet due to some arena allocations.

The main non-obvious change here is to static variable handling:
We can't destroy static_variables_ptr in destroy_op_array, as e.g.
that would clear the static variables in a dynamic function when
the op_array containing it is destroyed. Static variable destruction
is separated out for this reason (we already do static variable
destruction separately for normal functions, so we only need to
handle main scripts).

Closes GH-5595.

95a13ca989 Revert fix for bug 76813 and re2c version bump
CentOS 7 ships with re2c 0.13.5 by default, so we should not have
bumped the required re2c version to 0.13.7.  However, 0.13.5 does not
support default rules, so we cannot use them to fix bug 76813.
