DIOCGMEDIASIZE is supported and available since FreeBSD 5, it may

Purpose of this function is to open a path that is potentially pointing to a
block device or file without races. The function also proper open(3) flags
are used to check the device is not busy, and finally warning is been
printed if a block device happens to be misaligned.

I recently tried to mount an hfsplus file system from an image file with
a partition table by using the loop offset and sizelimit options to specify
the location of the file system.
hfsplus stores some metadata at a set offset from the end of the partition,
so it's sensitive to the device size reported by the kernel.
It worked with this:
But failed with this:
/dev/loop0: [0089]:2 (<imagefile>), offset 32768, sizelimit 102400000
/dev/loop1: [0089]:2 (<imagefile>), offset 32768, sizelimit 102400000
/proc/partitions shows the correct number of blocks to match the sizelimit.
But if I set a breakpoint in mount before the mount syscall, I could see:
102400000
102432768
The kernel loop driver will set the gendisk capacity of the device at
LOOP_SET_STATUS64 but won't sync it to the block device until one of two
conditions are met: All open file descriptors referring to the device are
closed (and it will sync when re-opened) or if the LOOP_SET_CAPACITY ioctl
is called to sync it. Since mount opens the device and passes it directly
to the mount syscall after LOOP_SET_STATUS64 without closing and reopening
it, the sizelimit argument is effectively ignroed. The capacity needs to
be synced immediately for it to work as expected.
This patch adds the LOOP_SET_CAPACITY call to loopctx_setup_device since
the device isn't yet released to the user, so it's safe to sync the capacity
immediately.

doesn't exist. Removed err.h include from all files, and included err.h from
c.h instead if it exists, otherwise alternatives are provided.

The current implementation uses fixed sector size (512 bytes), that's
wrong. UEFI standard requires real logical sector size -- it means
BLKSSZGET for Linux.
The size of GPT header is not static, but whole sector is allocated
for the header. In theory the HeaderSize field could be greater than
sizeof(struct gpt_header). It means we have to read whole sector with
the header, because the header crc32 checksum is counted according to
HeaderSize.
