Re-apply the part of r260022 that was reverted by r260030 with one significant difference: for LIB32 builds both TARGET_ARCH and MACHINE_ARCH are defined. TARGET_ARCH confusingly holds the architecture of the host (e.g. amd64), while MACHINE_ARCH holds the architecture were trying to build (e.g. i386). With both set and different, r260022 changed the behaviour to interpret the condition as building a cross-amd64 libkvm on i386, when obviously we're trying to build an i386 version on amd64. When COMPAT_32BIT is defined, we're building LIB32 and ignore the value of TARGET_ARCH as we did before.

Use __SCCSID for SCCS IDs in libkvm sources. Rather than using #ifdef's around a static char array, use the existing helper macro from <sys/cdefs.h> for SCCS IDs. To preserve existing behavior, add -DNO__SCCSID to CFLAGS to not include SCCS IDs in the built library by default.

Add support to libkvm for reading vmcores from other architectures. - Add a kvaddr_type to represent kernel virtual addresses instead of unsigned long. - Add a struct kvm_nlist which is a stripped down version of struct nlist that uses kvaddr_t for n_value. - Add a kvm_native() routine that returns true if an open kvm descriptor is for a native kernel and memory image. - Add a kvm_open2() function similar to kvm_openfiles(). It drops the unused 'swapfile' argument and adds a new function pointer argument for a symbol resolving function. Native kernels still use _fdnlist() from libc to resolve symbols if a resolver function is not supplied, but cross kernels require a resolver. - Add a kvm_nlist2() function similar to kvm_nlist() except that it uses struct kvm_nlist instead of struct nlist. - Add a kvm_read2() function similar to kvm_read() except that it uses kvaddr_t instead of unsigned long for the kernel virtual address. - Add a new kvm_arch switch of routines needed by a vmcore backend. Each backend is responsible for implementing kvm_read2() for a given vmcore format. - Use libelf to read headers from ELF kernels and cores (except for powerpc cores). - Add internal helper routines for the common page offset hash table used by the minidump backends. - Port all of the existing kvm backends to implement a kvm_arch switch and to be cross-friendly by using private constants instead of ones that vary by platform (e.g. PAGE_SIZE). Static assertions are present when a given backend is compiled natively to ensure the private constants match the real ones. - Enable all of the existing vmcore backends on all platforms. This means that libkvm on any platform should be able to perform KVA translation and read data from a vmcore of any platform.

Implement kvm_kerndisp This change adds a new libkvm function, kvm_kerndisp(), that can be used to retrieve the kernel displacement, that is the difference between the kernel's base virtual address at run time and the kernel base virtual address specified in the kernel image file. This will be used by kgdb, to properly relocate kernel symbols, when needed. Reviewed by: jhb Differential Revision: https://reviews.freebsd.org/D23285
