Change 127646 by jb@jb_freebsd1 on 2007/10/18 02:13:15

	The start of a BSD licensed libdwarf.
	
	The API differs from the GNU libdwarf (from SGI) which
	differs from the GNU libdwarf (from Red Hat).
	
	The functionality here so far is adequate for DTrace's
	CTF tools. The client does not need to keep track of
	allocated memory like the GNU versions do.
	
	This code assumes the use of FreeBSD's libelf. In particular
	it assumes that it is OK to open an ELF file read-only,
	call elf_getdata() and then modify the in-memory data buffer.
	This is important because any optimisation level in gcc
	causes the generation of debug sections with RELA sections.
