1-4,6,7 are small cleanups.
5 fixes a potential segfault.
8 fixes a use after free for dso->long_name
9 avoids a segfault in elfutils when a truncated elf is loaded.
10 properly tracks that a dso had symbols loaded from a vmlinux image
11-16 fix handling of the '.opd' section in the presence of debuginfo. They should also fix plt symbol synthesis (haven't seen the plt issues in practice).

Changes from v1: - rebased on top of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git perf/core - In #2, make the symbols have size 0 instead of 1.
