a3b72067de Add checking for sparse file format 
Sparse file can come from an untrusted source.
Need more checking to ensure that it is not a malformed
file and would not cause any OOB read access.

Update fuzz test for decoding also.

Test: adb reboot fastboot
      fuzzy_fastboot --gtest_filter=Fuzz.Sparse*
      fuzzy_fastboot --gtest_filter=Conformance.Sparse*
      sparse_fuzzer

50e6029a4e libsparse: Add method to create sparse file from buffer 
Refactor elements of sparse file parsing that depend on
an fd into SparseFileSource class, then create implementations
using both fd and buffer. Add sparse_file_read_buf which
reads the given buffer into a sparse file cookie without
copying.

Test: flash system with sparse images

a7eeb22efb libsparse: Fix verbose_error string usage 
Switch vnsprintf to StringPrintf to avoid off-by-one, and switch
sparse_read.c to cpp.

Test: fastboot flash normal image with smaller sparse limit
