0643301c75 Don't perform recursive get_gc call
On further consideration, we should be making use of the fact
that zend_object_iterator is also a zend_object here, and let
GC handle the get_gc call on it. Calling get_gc recursively like
this is generally not safe, because there is only one gc_buffer.

This also happens to be much simpler...

15fafcd664 Expose inner dual_it iterator to GC
Moving the zend_iterator_dtor from dual_it_dtor to dual_it_free_storage
exposed this GC leak in an existing test. Forward the result of the
iterator get_gc to the dual_it get_gc.

3e01f5afb1 Replace zend_bool uses with bool
We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.

Of course, zend_bool is retained as an alias.

48a34bc120 Add helper APIs for get_gc implementations
get_gc() implementations that need to explore heterogeneous data
currently work by computing how many GC entries they need,
allocating a buffer for that and storing it on the object. This
is inefficient and wastes memory, because the buffer is retained
after the GC run.

This commit adds an API for a single global GC buffer, which can
be reused by get_gc implementations (as only one get_gc call is
ever active at the same time). The GC buffer will automatically
grow during the GC run and be discarded at the end.

92ac598aab Remove local variables
This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.

A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.

This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.

With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.

Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files.  All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.

8d3f8ca12a Remove unused Git attributes ident
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.

d11734b4b0 reworked the patch, less new stuff but worky
TLS is already used in TSRM, the way exporting the tsrm cache through
a thread local variable is not portable. Additionally, the current
patch suffers from bugs which are hard to find, but prevent it to
be worky with apache. What is done here is mainly uses the idea
from the RFC patch, but

- __thread variable is removed
- offset math and declarations are removed
- extra macros and definitions are removed

What is done merely is

- use an inline function to access the tsrm cache. The function uses
  the portable tsrm_tls_get macro which is cheap
- all the TSRM_* macros are set to placebo. Thus this opens the way
  remove them later

Except that, the logic is old. TSRMLS_FETCH will have to be done once
per thread, then tsrm_get_ls_cache() can be used. Things seeming to be
worky are cli, cli server and apache. I also tried to enable bz2
shared and it has worked out of the box. The change is yet minimal
diffing to the current master bus is a worky start, IMHO. Though will
have to recheck the other previously done SAPIs - embed and cgi.

The offsets can be added to the tsrm_resource_type struct, then
it'll not be needed to declare them in the userspace. Even the
"done" member type can be changed to int16 or smaller, then adding
the offset as int16 will not change the struct size. As well on the
todo might be removing the hashed storage, thread_id != thread_id and
linked list logic in favour of the explicit TLS operations.
