5e53a4f90f lib: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

df57947f08 spdx: initial adoption of licensing ID tags.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Initially, only tag files that use BSD 4-Clause "Original" license.

a94a63f0a6 An MMC/SD/SDIO stack using CAM
Implement the MMC/SD/SDIO protocol within a CAM framework. CAM's
flexible queueing will make it easier to write non-storage drivers
than the legacy stack. SDIO drivers from both the kernel and as
userland daemons are possible, though much of that functionality will
come later.

Some of the CAM integration isn't complete (there are sleeps in the
device probe state machine, for example), but those minor issues can
be improved in-tree more easily than out of tree and shouldn't gate
progress on other fronts. Appologies to reviews if specific items
have been overlooked.

A previous iteration of the tests I added in r319844 involved free(3), but

33193da27e Fix up r316081 by using nitems(cam_errbuf) instead of sizeof(cam_errbuf)
Part of my original reasoning as far as converting the snprintf
calls was to permit switching over from char[] to wchar_t[] in the
future, as well as futureproof in case cam_errbuf's size was ever
changed.

Unfortunately, my approach was bugged because it conflated the
number of items with the size of the buffer, instead of the number of
elements being a fixed size != 1 byte.

Use nitems(..) instead which counts the quantity of items of a specific
type, as opposed to an unqualified sizeof(..) (which assumes that the
number of characters is equal to the buffer size).

b0b1dbdd49 Start adding basic tests for cam(3)
This change contains several negative and positive tests for:
- cam_open_device
- cam_close_device
- cam_getccb
- cam_freeccb

This also contains a test for the failure case noted in bug 217649,
i.e., O_RDWR must be specified because pass(4) requires it.

This test unfortunately cannot assume that cam-capable devices are
present, so the user must explicitly provide a device via
`test_suites.FreeBSD.cam_test_device`. In the future, a test kernel
module might be shipped, or ctl(4) might be used, as a test device
when testing out libcam, which will allow the tests to do away with
having to specify an explicit test device.

95320acebc Fix multiple Coverity Out-of-bounds access false postive issues in CAM
The currently used idiom for clearing the part of a ccb after its
header generates one or two Coverity errors for each time it is
used.  All instances generate an Out-of-bounds access (ARRAY_VS_SINGLETON)
error because of the treatment of the header as a two element array,
with a pointer to the non-existent second element being passed as
the starting address to bzero().  Some instances also alsp generate
Out-of-bounds access (OVERRUN) errors, probably because the space
being cleared is larger than the sizeofstruct ccb_hdr).

In addition, this idiom is difficult for humans to understand and
it is error prone.  The user has to chose the proper struct ccb_*
type (which does not appear in the surrounding code) for the sizeof()
in the length calculation.  I found several instances where the
length was incorrect, which could cause either an actual out of
bounds write, or incompletely clear the ccb.

A better way is to write the code to clear the ccb itself starting
at sizeof(ccb_hdr) bytes from the start of the ccb, and calculate
the length based on the specific type of struct ccb_* being cleared
as specified by the union ccb member being used.  The latter can
normally be seen in the nearby code.  This is friendlier for Coverity
and other static analysis tools because they will see that the
intent is to clear the trailing part of the ccb.

Wrap all of the boilerplate code in a convenient macro that only
requires a pointer to the desired union ccb member (or a pointer
to the union ccb itself) as an argument.
