EXP-1122 FIX (Viewer) LLQtWebKit should support a JavaScript/content debugger to help content creators
Viewer side changes to enable Web debugger.

EXP-1111 FIX LLQtWebKit (and related media system) should log events, progress etc. to make debugging problems easier

fix files that do not end with a newline (warn-on-failure:copyright because some have both problems...)

paypal had a verisign -2 CA cert, and the new trust list only includes -3.

Also, disable use of the system cert store.  Just use our list.

EXP-676 FIX As a web developer, I want to access information about the current state of the SL client, such as avatar location

Reverted Linux LLQtWebKit to older version which triggered warnings here that are treated as errors.

(Included refs to new LLQtWebKit that supports functionality)

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.

License fixes (GPL -> LGPL). And typo in comments.
Addresses merov's comments on the review board.

***

Added Merov's compile fixes for windows.

If Qt and/or llqtwebkit is found in a non-standard place, you still
have to set LD_LIBRARY_PATH yourself (to $QTDIR/lib) before running
the viewer of course (or the webkit plugin will silently fail).

Latest traunch of fixes to new Web only content floater
Also removed line in test app that fails to build - have a note to fix later

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.

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.

(Monroe's code - I made a patch and copied it over from viewer-skylight branch)

original commit log for acb451f83a9d was: "Temporary changes to allow the viewer to build against an older version of llqtwebkit.
NOTE: once updated builds of llqtwebkit are available on all platforms, this changeset should be backed out."

So, yes, I'm backing that out.
