Add NVMe CCB (union ccb / struct ccb_nvmeio) building functions for the four NVMe reservation opcodes, Format NVM, and Get Features / Set Features. These use the nvme_command building blocks added to sys/dev/nvme/nvme.h, and are used by the new camcontrol(8) nvres, nvformat and nvfeature subcommands that will be added separately. sys/cam/nvme/nvme_all.c: Add NVMe CCB building functions for the four NVMe reservation opcodes: nvme_resv_report(), nvme_resv_register(), nvme_resv_acquire() and nvme_resv_release(). Data direction is set internally (CAM_DIR_IN or CAM_DIR_OUT as appropriate), so no flags parameter is needed. Add a new nvme_format() CCB building function. Add nvme_get_feature() and nvme_set_feature() CCB building functions, along with nvme_get_feature_hostid() and nvme_set_feature_hostid() convenience wrappers for the hostid feature. nvme_set_feature_hostid() takes an sv argument so the caller can request that the hostid persist across reset. sys/cam/nvme/nvme_all.h: Add prototypes for the above. Wrap the declarations in __BEGIN_DECLS / __END_DECLS so C++ compilers don't mangle the names of the C symbols.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
