dd(1): neutralize SIGINT while non-async-signal safe code is executing making the SIGINT handler (the terminate() function) safe to execute at any interruption moment. This fixes a race in 5807f35c541c26bbd91a3ae12506cd8dd8f20688 where SIGINT delivered right after the check_terminate() but before a blocking syscall would not cause abort. Do it by setting the in_io flag around potentially blocking io syscalls. If handler sees the flag, it terminates the program. Otherwise, termination is delegated to the before_io/after_io fences.

dd: Fix SIGINT handling. Currently, we handle SIGINT by calling summary() and _exit() directly from the signal handler, which we install after setup(). There are several issues with this: * summary() is not signal safe; * the parent is not informed about the signal; * setup() can block on open(), and catching SIGINT at that stage will produce the correct exit status but will not print anything to stderr as POSIX demands. Fix this by making SIGINT non-restartable, changing our signal handler to only set a flag, installing it before setup(), and checking the termination flag before and after every blocking operation, i.e. open(), read(), write(). Also add two test cases, one for catching SIGINT while opening the input and one for catching it while reading. I couldn't think of an easy way to test catching SIGINT while writing (it's certainly feasible, but perhaps not from a shell script). MFC after: 1 week Sponsored by: Klara, Inc.

General further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 3-Clause license. 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.

Create the altix project branch. The altix project will add support for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting is a two-module system, consisting of a base compute module and a CPU expansion module. SGI's NUMAFlex architecture can be an excellent platform to test CPU affinity and NUMA-aware features in FreeBSD.

Even more cleanups to dd(1). This is probably the culmination of the BDEification process of dd(1). Most of the changes are from BDE's archive. Support for negative offsets is gone again, but the case where you lseek() onto byte -1 of something from a negative offset using seek/skip is fixed; if you end up on -1, you won't get a false positive lseek failure. The biggest changes are to data types (more size_t, for instance) and argument parsing. skip/seek on /dev/{,k}mem now occurs (instead of "read until you reach the offset") due to mem devices now being D_DISK. Some const things are now correctly declared as such, and the "case table" building is better. The only thing that seems to be left to make dd(1) everything TOG wants it to be is l10n.
