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 Kernel Source:
This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.
Kernel configuration files are located in the conf/ subdirectory of each
architecture. GENERIC is the configuration used in release builds. NOTES
contains documentation of all possible entries. LINT is a compile-only
configuration used to maximize build coverage and detect regressions.
Documentation:
Source code documentation is maintained in a set of man pages, under section 9.
These pages are located in share/man/man9, from the
top-level of the src tree. Consult intro(9)
for an overview of existing pages.
Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
