Import C startup files for ELF support. Submitted by: John Polstra <jdp@polstra.com>

Remove the sed hack for ABI tag notes. The ELF notes compiled in C were placed in a section with the wrong type (SHT_PROGBITS instead of SHT_NOTE). Previously, sed was used on the generated assembly to rewrite the section type. Instead, write the notes in assembly which permits setting the correct section type directly. While here, move inline assembly entry points out of C and into assembly for aarch64, arm, and riscv.

Let all .c and .S files under lib/csu consistently use the __FBSDID() macro for identification, instead of several different hand-rolled variants (plain .ident, .ascii, etc).

Stop calling _init/_fini methods from crt1 for dynamic binaries. Do call preinit, init and fini arrays methods from crt1 for static binaries. Mark new crt1 with FreeBSD-specific ELF note. Move some common crt1 code into new MI file ignore_init.c, to reduce duplication. Also, conservatively adjust nearby sources for style.
