62491cc719 Many fixes to get (remote) dynamic unwind info working for real.
Add get_proc_name() callback to accessors so things like the ptrace-support
routines can also print static procedure names.
Try running "tests/test-ptrace -v -t tests/ia64-test-dyn1" for fun.

4577631094 Don't be verbose by default.
(main): Send SIGUSR1 before dynamic testing starts, SIGUSR2 afterwards (makes it
	easy for test-ptrace to catch when verification should begin).
	Add test case for func_vframe().

Skip over "prev_addr".  Read start/end-IP directly into the "di" structure,
	not into temporary variables.  Skip padding by directly adjusting the
	address (don't bother fetching padding values; that only slows things down).
	Return 0 only if we really did find dynamic unwind info.

a01d77efb8 Fix a bug that kept unw_get_proc_name() from working for the UNW_LOCAL_ONLY case.
Allow region-length to be negative in dynamic region info.  This is used to

for such epilogues, regardless of the size of a procedure.

Start working on a dynamic unwind-info tester.
