accessed through the static LLThread::tldata().
Currently this object contains two (public) thread-local
objects: a LLAPRRootPool and a LLVolatileAPRPool.

The first is the general memory pool used by this thread
(and this thread alone), while the second is intended
for short lived memory allocations (needed for APR).
The advantages of not mixing those two is that the latter
is used most frequently, and as a result of it's nature
can be destroyed and reconstructed on a "regular" basis.

This patch adds LLAPRPool (completely replacing the old one),
which is a wrapper around apr_pool_t* and has complete
thread-safity checking.

Whenever an apr call requires memory for some resource,
a memory pool in the form of an LLAPRPool object can
be created with the same life-time as this resource;
assuring clean up of the memory no sooner, but also
not much later than the life-time of the resource
that needs the memory.

Many, many function calls and constructors had the
pool parameter simply removed (it is no longer the
concern of the developer, if you don't write code
that actually does an libapr call then you are no
longer bothered with memory pools at all).

However, I kept the notion of short-lived and
long-lived allocations alive (see my remark in
the jira here: https://jira.secondlife.com/browse/STORM-864?focusedCommentId=235356&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-235356
which requires that the LLAPRFile API needs
to allow the user to specify how long they
think a file will stay open. By choosing
'short_lived' as default for the constructor
that immediately opens a file, the number of
instances where this needs to be specified is
drastically reduced however (obviously, any
automatic LLAPRFile is short lived).

Addressed Boroondas remarks in https://codereview.secondlife.com/r/99/
regarding (doxygen) comments. This patch effectively only changes comments.

Includes some 'merge' stuff that ended up in llvocache.cpp
(while starting as a bug fix, now only resulting in a cleanup).

***

Added comment 'The use of apr_pool_t is OK here'.

Added this comment on every line where apr_pool_t
is correctly being used.

This should make it easier to spot (future) errors
where someone started to use apr_pool_t; you can
just grep all sources for 'apr_pool_t' and immediately
see where it's being used while LLAPRPool should
have been used.

Note that merging this patch is very easy:
If there are no other uses of apr_pool_t in the code
(one grep) and it compiles, then it will work.

***

Second Merge (needed to remove 'delete mCreationMutex'
from LLImageDecodeThread::~LLImageDecodeThread).

***

Added back #include <apr_pools.h>.

Apparently that is needed on libapr version 1.2.8.,
the version used by Linden Lab, for calls to
apr_queue_*. This is a bug in libapr (we also
include <apr_queue.h>, that is fixed in (at least) 1.3.7.

Note that 1.2.8 is VERY old. Even 1.3.x is old.

Added the necessary plumbing to get link_hovered events from the webkit plugin through to the viewer UI.

This requires a llqtwebkit library built from revision 1799a899e06d or later in http://hg.secondlife.com/llqtwebkit to function.  The viewer source changes are backwards-compatible with earlier versions of llqtwebkit, it just won't see any link_hovered events with previous revisions.

Reviewed by Callum.

Added support to the webkit media plugin and llpluginclassmedia for passing through the auth request/response.  We still need an updated build of llqtwebkit for all platforms, as well as some UI work in the viewer to actually display the auth dialog.

Added support for a media plugin message that asks the viewer to open a file picker on the plugin's behalf.

LLPluginProcessParent can now optionally use a separate thread for reading messages from plugin sockets.  If this is enabled, it will spawn a single thread and use apr_pollset_poll to wake up the thread when incoming data arrives instead of polling all the descriptors round-robin every frame.  This should be somewhat more efficient, and should also allow blocking requests from plugins to be serviced much more quickly (once we start using them).  This is currently disabled by default, until it's had a bit more focused testing on multiple platforms.

Hooked up the switch to use the message read thread to the PluginUseReadThread debug setting and an item in the Advanced menu in the viewer, and to a checkbox in the UI in llmediaplugintest.

Updated some debug logging in the plugin system to have appropriate tags and not log dire-looking warnings during normal operation.

LLPluginProcessParent now once again explicitly kills plugin processes (instead of just closing their sockets and waiting for them to exit).  The problem we were attempting to solve by not doing the kill (letting the webkit plugin write its cookie file on exit) has been solved another way.

LLPluginProcessParent::sendMessage() now attempts to write the outgoing message to the socket immediately instead of waiting for the next frame.  This should reduce the latency of sending plugin messages.

Added a separate fast timer for LLViewerMedia::updateMedia().

This bugs me in a minor way.  Did a search-and-cleanup on various swear words.

Added an "init" message in LLPLUGIN_MESSAGE_CLASS_MEDIA, and made LLPluginClassMedia queue it up before initializing its LLPluginProcessParent.
Made all existing plugins send their texture_params message from this init message instead of the LLPLUGIN_MESSAGE_CLASS_BASE "init" message.  (This ensures that they won't start to receive 'size_change' messages until after the init has happened.)
Added "set_user_data_path" and "set_language_code" messages to LLPluginClassMedia.
Made webkit plugin deal with the new messages, when they're sent before it receives the media "init".
Removed the user_data_path and language_code arguments from the init function calls throughout the hierarchy.
Made LLViewerMediaImpl queue up the language code and user data path messages before initializing the media.

Not part of the client and nothing here is deployed - internal testing only.

Added an LLSD argument to LLPluginClassMedia::keyEvent() and LLPluginClassMedia::textInput() which contains the native key data.
Made LLViewerMediaImpl retrieve the native key data and pass it to keyEvent and textInput.
Added a native_key_data parameter to the text_event and key_event messages.
Made the webkit plugin extract the native_key_data parameter and pass it to the internal keyEvent() and unicodeInput() functions.
Fixed LLMediaPluginTest to match function signature change to LLPluginClassMedia::keyEvent().
