A new sysdecode_syscallname() function accepts a system call code and returns a string of the corresponding name (or NULL if the code is unknown). To support different process ABIs, the new function accepts a value from a new sysdecode_abi enum as its first argument to select the ABI in use. Current ABIs supported include FREEBSD (native binaries), FREEBSD32, LINUX, LINUX32, and CLOUDABI64. Note that not all ABIs are supported by all platforms. In general, a given ABI is only supported if a platform can execute binaries for that ABI. To simplify the implementation, libsysdecode's build reuses the existing pre-generated files from the kernel source tree rather than duplicating new copies of said files during the build. kdump(1) and truss(1) now use these functions to map system call identifiers to names. For kdump(1), a new 'syscallname()' function consolidates duplicated code from ktrsyscall() and ktrsyscallret(). The Linux ABI no longer requires custom handling for ktrsyscall() and linux_ktrsyscall() has been removed as a result.
