Disable getenv() in libjpeg and libjpeg_turbo (roll to 238232)

getenv() is used in libjpeg and libjpeg_turbo to get environment
variable JPEGMEM which overrides the default max_memory setting from
jpeg_mem_init. However, getenv() is not thread-safe. Now libjpeg may
be called from multiple threads when impl-side-painting is enabled.

Revert 225751 "BitmapContentLayerUpdater shouldn't reallocate bi..."

> BitmapContentLayerUpdater shouldn't reallocate bitmap smaller.
> 
> BitmapContentLayerUpdater was always allocating a new bitmap if the size of the region to be drawn changed, even if the new region was smaller. These unnecessary reallocations can be very expensive because they require page faults and for the operating system to clear out the memory.
