4f7faac8d7 Use static_cast to cast pointers returned by malloc/calloc/realloc/mmap.
static_cast is preferable to reinterpret_cast when casting from void*
pointers returned by malloc/calloc/realloc/mmap calls.

Discovered while looking at compiler warnings (b/26936282).

Test: WITH_TIDY=1 WITH_STATIC_ANALYZER=1 mma

0779fc9814 imgdiff: skip spurious gzip headers in image files
dragon kernel is compressed via lz4 for boot speed and bootloader
support reasons and recent prebuilts happen to include the gzip header
sequence which is causing imgdiff to fail.

Detect a spurious gzip header and treat the section as a normal section.

a91c66d7c1 imgdiff: fix file descriptor leak
mkstemp() allocates a file description that is never released.  If
MakePatch() is called too many time, imgdiff reaches the Operating
System EMFILE (too many open files) limit.
