Make _eprol (and _etext) hidden. Fixes "cc -pg" on arm64 where the current code which has a local _eprol label in the inline asm and a global _eprol declaration results in an incorrect relocation. This also removes an unnecessary relocation on hppa (and possible on other architectures as well). ok guenther@

Split out the hppa and mips64 versions of boot.h similar to how I split ld.so/boot.c in 2019: * delete extraneous #includes * delete jmprel handling on non-hppa * delete RELOC_GOT() and DT_PROC bits on non-mips64 ok visa@

ld.so boot cleanup support: - put functions and data which are only used before calling the executable's start function into their own page-aligned segments for unmapping (only done on amd64, arm64, armv7, powerpc, and sparc64 so far) - pass .init_array and .preinit_array functions an addition argument which is a callback to get a structure which includes a function that frees the boot text and data - sometimes delay doing RELRO processing: for a shared-object marked DF_1_INITFIRST do it after the object's .init_array, for the executable do it after the .preinit_array - improve test-ld.so to link against libpthread and trigger its initialization late libc changes to use this will come later ok kettenis@

Rearrange C runtime bits: now that ld.so exports environ and __progname, move their definitions and initialization in static links to libc.a Make crt0 always invoke a new func _csu_finish() in libc to process the auxv and to either register the ld.so cleanup function (in dynamic links) or initialize environ and __progname and do MC_DISABLE_KBIND (in static links). In libc, get pagesize from auxv; cache that between getpagesize() and sysconf(_SC_PAGESIZE) ok mpi@ "good time" deraadt@

Introduce new csu0 variant for -static -pie binaries to use called rcsu0.o where the initial 'r' is for relocatable. rcsu0.o performs self-relocation on static pie binaries by calling a slightly modified copy of ld.so's _dl_boot_bind() in boot.h. The first arch implementatation is also included for amd64 where __start calls _dl_boot_bind() and then calls ___start(). Includes parts from kettenis@ to help get R_X86_64_64 relocations working and proper handling for undefined weak symbols. This is the first part of several to get static pie self-relocating binaries working. binutils, gcc and kernel changes are forthcoming to complete the solution, then per-arch implementations are needed for MD_RCRT0_START in csu. okay kettenis@ pascal@ deraadt@
