Refactor sparse file support into libsparse Minimal refactoring of output_file.c into libsparse in preparation for completely separating libsparse from ext4_utils. Moves output_file.c, backed_block.c, and parts of ext4_utils.c into libsparse. The only changes to the remanining files in ext4_utils are using the new sparse.h header, and moving the wipe call out of output_file.c and into make_ext4fs.c.

Pass file descriptor instead of file name Passing a file descriptor to make_ext4fs_internal() is more flexible. We can use tmpfile() to create a temporary file. tmpfile() is better than other solutions because it unlinks the file right after creating it, so closing fd effectively removes temp file. Thus we don't have to worry about large temp files accidently left on the filesystem in case of the program crash. Change-Id: Iba3758a0e13a898920d30d7fa5da696c22daa2b7

Bug fixes to make_ext4fs Fix definition of uuid struct. Properly set the block_group number in each backup copy of the superblock. Adjust the info.total_inodes field after rounding up the inodes per block group. Add the option -t to initialize all the inode tables. If also specified with the -s option, use the CHUNK_TYPE_FILL sparse records to initialize them. Change-Id: Idd8bcee1b9bde3e82ad8da89ef974fbc12d7a6c6

Implement poor man's exception handling to prevent errors from killling recovery make_ext4fs was originally designed to be a standalone program, and the error() macro calls exit() after printing a diagnostic. However, when it was turned into a library that recovery links against, calling exit() kills the entire recovery process, which the kernel starts back up, which dies, and the cycle continues. This changes make_ext4fs to use setjmp() early, and changes error to use longjmp to return to that point. When longjmp is called, the error handler just returns an error. If it was invoked as a standalone program, this causes the program to exit with an error. If it was invoked as a library function, the error return is gracefully handled by recovery.

ext4_utils: Add support for wipe option, and wipe by default in recovery Adds a -w option to make_ext4fs, which will attempt to use the BLKSECDISCARD ioctl to erase the partition in order to avoid leaving old data where it could be recovered, and to improve wear levelling after a reformat. Also causes factory reset through recovery to do a wipe. Change-Id: Ibe34bbd84552e526be6bd041024a950806aca6b4

Add the ability to specify a reserved space size when making filesystems. If you specify a negative length when making a filesystem, then the filesystem size is the size of the partiton (or image file) minus the absolute value of the negative length specified.

Add support for sparse ext4 image creation. This adds the -s option to the make_ext4fs tool, which now creates "sparse" filesystem images, which is very useful for the large 32 Gbyte filesystems we are now building. This check-in also fixes make_ext4fs to properly create filesystems larger thatn 4 Gbytes on 64-bit Linux, 32-bit android and Macs. Change-Id: Ie5838492fcf944f5c875481693c0dbd7013deae4

Fix calculation of dentry size The PAD_TO function was incorrectly handling values that were already aligned, which could lead to overruns of the dentry block.
