1747e1d875 Fix incorrect error message in geom map
If geom_map fails to find the end of a mapped partition based on a search, it would return the incorrect error message, stating it could not parse the START value

28d507fcec Fix the label search routine in geom_map to not trip up on '\0' bytes.
* Just do the buf check early and fail out
* If the offset being searched is:

00110000  00 b5 7e 45 61 e2 76 d3  c1 78 dd 15 95 cd 1f f1  |..~Ea.v..x......|

.. and the match string is '.!/bin/sh'

.. then it'll set the match string[0] to '\0', do a strncmp() against
the read buffer, find it's matching two zero-length strings, and think
that's where to start.

5f23eb4d9c Add device name used in geom_map verbose output. This helps when using
geom_map with multiple flash/spi devices.

c60fd25d34 Updates to geom_map from the author.
The major update here is to support 64 bit size/offsets.
There's also style related changes.

27afdbaa51 Introduce geom_map, a GEOM provider designed for use by
embedded flash stores.

Some devices - notably those with uboot - don't have an
explicit partition table (eg like Redboot's FIS.)
geom_map thus provides an easy way to export the hard-coded
flash layout as geom providers for use by filesystems and
other tools.

It also includes a "search" function which allows for
dynamic creation of partition layouts where the device only
has a single hard-coded partition. For example, if
there is a "kernel+rootfs" partition, a single image can
be created which appends the rootfs after the kernel with
an appropriate search string. geom_map can be told to
search for said search string and create a partition
beginning after it.
