Fix crashes in function registration + test
Internal function won't need their refcount increased as they outlive
the debugger session, and userland functions won't be unloaded either.
So no refcount management is necessary for registered functions.

Fix GH-15208: Segfault with breakpoint map and phpdbg_clear()
It crashes because it's gonna try accessing the breakpoint which was cleared
by user code in `phpdbg_clear();`. Not all breakpoint data was properly
cleaned.

Closes GH-16953.

Fix GH-16181: phpdbg: exit in exception handler reports fatal error
When running PHP code, we must not handle `UnwindExit` exceptions, but
rather have to ignore them.

New hash tables are not automatically packed, so we must not treat them
as such.  Therefore we guard the foreach appropriately.

Fix GH-14553: Bug in phpdbg8.3 (also 8.1 and 8.2) echo output - trimmed at NULL byte (?)
This broke in 6318040df2 when phpdbg
stopped using its custom printing routines. By relying on standard
printing routines, the embedded NUL bytes are causing the strings to be
cut off, even when using %.*s. Solve this by going straight to the
output routine, which is what the printf routine would've done anyway.

Fix GH-13931: Applying zero offset to null pointer in Zend/zend_opcode.c
In the test cases, the compiler bails out due to a fatal error.
The data structures used by the compiler will contain stale values.
In particular, for the test case CG(loop_var_stack) will contain data.
The next compilation will incorrectly use elements from the previous
stack.
To solve this, we reset part of the compiler data structures.
We don't do a full re-initialization via init_compiler() because that will
also reset streams and resources.

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.

Fix GH-10489: run-tests.php does not escape path when building cmd (#10560)
Multiple tests had to be changed to escape the arguments in shell
commands. Some tests are skipped because they behave differently with
spaces in the path versus without. One notable example of this is the
hashbang test which does not work because spaces in hashbangs paths are
not supported in Linux.

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.

Improve tests on 32bit
The watch_*.phpt test apparently no longer fail on 32bit, so we remove
the XFAIL conditions.  bug77269.phpt is practically identical to
bug77272.phpt, and there seems no particular reason to have an
additional test for libgd ≤ 2.2.5.

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.

CentOS 7 ships with re2c 0.13.5 by default, so we should not have

support default rules, so we cannot use them to fix bug 76813.
