* Fix known issues which blow up the process after dlopen("libthr.so")kib2015-01-182-6/+24
| | | | | | | | | | | | | | | | | | | | | (or loading a dso linked to libthr.so into process which was not linked against threading library). MFC r276630: Remove interposing, fix malloc, reinstall signal handlers wrappers on libthr load. MFC r276681: Avoid calling internal libc function through PLT or accessing data though GOT. MFC r277032: Reduce the size of the interposing table and amount of cancellation-handling code in the libthr. MFC note: r276646 ("do not erronously export 'openat' symbol from rtld") is not applicable to stable/10 yet, since PATHFDS support was not merged.

In particular, this can lead to errors when building world with clang and -g, similar to: /usr/obj/usr/src/tmp/usr/lib/libc.so: undefined reference to `_malloc_options' Reported by: Conrad J.

| | | | | | | | | prior to 3.0.0 release). This fixes several bugs related to memory initialization. Mangle __jemalloc_a0{malloc,calloc,free}() just like all the other library-internal symbols in jemalloc, and adjust the tls allocation code in libc to use the mangled names.
