f2a520f48d clean up error output;

4211384976 Switch ogle to in-tree gosym package. Delete my private sym 
package.  If a Sym is a function symbol, include a reference
to the Func so it's easily accessible when you're traversing
the list of all symbols.  This diff is more interesting than
the proc switch because the gosym interface differs from the
old sym interface.

1b14bdbf1c changes to accommodate nacl: 
* change ldt0setup to set GS itself; nacl won't let us do it.
  * change breakpoint to INT $3 so 8l can translate to HLT for nacl.
  * panic if closure is needed on nacl.
  * do not try to access symbol table on nacl.
  * mmap in 64kB chunks.

nacl support:
  * system calls, threading, locks.
