792da6f338 - Replace thread safety fixes that I accidentally didn't check in when the

   - Add LM locking to go with JS_BeginRequest stuff

// The icon decoder is a decoder specifically tailored for loading icons
// from the OS. We've defined our own little format to represent these icons
// and this decoder takes that format and converts it into 24-bit RGB with alpha channel
// support. It was modeled a bit off the PPM decoder.
//
// Assumptions about the decoder:
// (1) We receive ALL of the data from the icon channel in one OnDataAvailable call. We don't
// support multiple ODA calls yet.
// (2) the format of the incoming data is as follows:
// The first two bytes contain the width and the height of the icon.
// Followed by 3 bytes per pixel for the color bitmap row after row. (for heigh * width * 3 bytes)
// Followed by bit mask data (used for transparency on the alpha channel).

/*-----------------------------------------------------------------------------
* This is the callback routine from the IJG JPEG library used to supply new
* data to the decompressor when its input buffer is exhausted. It juggles
* multiple buffers in an attempt to avoid unnecessary copying of input data.
*
* (A simpler scheme is possible: It's much easier to use only a single
* buffer; when fill_input_buffer() is called, move any unconsumed data
* (beyond the current pointer/count) down to the beginning of this buffer and
* then load new data into the remaining buffer space. This approach requires
* a little more data copying but is far easier to get right.)
*
* At any one time, the JPEG decompressor is either reading from the necko
* input buffer, which is volatile across top-level calls to the IJG library,
* or the "backtrack" buffer. The backtrack buffer contains the remaining
* unconsumed data from the necko buffer after parsing was suspended due
* to insufficient data in some previous call to the IJG library.
*
* When suspending, the decompressor will back up to a convenient restart
* point (typically the start of the current MCU). The variables
* next_input_byte & bytes_in_buffer indicate where the restart point will be
* if the current call returns FALSE. Data beyond this point must be
* rescanned after resumption, so it must be preserved in case the decompressor
* decides to backtrack.
*
* Returns:
* TRUE if additional data is available, FALSE if no data present and
* the JPEG library should therefore suspend processing of input stream

* just return) and for non-interlaced images (it just does the
* memcpy for you) if it will make the code easier. Thus, you
* can just do this for all cases:
*
* png_progressive_combine_row(png_ptr, old_row, new_row);
*
* where old_row is what was displayed for previous rows. Note
* that the first pass (pass == 0 really) will completely cover
* the old row, so the rows do not have to be initialized. After
* the first pass (and only for interlaced images), you will have
* to pass the current row, and the function will combine the
