* runtime/task_finder_vma.c (stap_remove_vma_map_info): Return negative
status on failure.
(stap_find_vma_map_info): Likewise.
(stap_find_vma_map_info_user): New function.
(stap_drop_vma_maps): New function.
* runtime/sym.h (addr): Renamed to static_addr, to store addresses for
sections which are always mapped at the same address.
(_stp_module_relocate): Add extra struct task_struct *tsk argument.
* runtime/sym.c (_stp_tf_exec_cb): New callback, calls stap_drop_vma_maps.
(_stp_tf_mmap_cb): Don't store address in module.section, but call
stap_add_vma_map_info() per tsk->group_leader for matched module.
Don't register empty/null modules.
(_stp_module_relocate): Take extra struct task_struct *tsk argument,
cache last tsk used. Only use section->static_addr for none dynamic
modules. Use stap_find_vma_map_info_user() to locate dynamic modules.
(_stp_mod_sec_lookup): Add extra argument unsigned long *rel_addr to
optionally store relative address when module/section found.
(_stp_kallsyms_lookup): Use _stp_mod_sec_lookup to find relative address.
(_stp_sym_init): Register _stp_tf_exec_cb in stap_task_finder_target.
Add error check to see if task finder could be initialized.
* dwflpp.cxx (emit_address): Pass NULL for kernel/modules and current for
user tasks to _stp_module_relocate.
* runtime/transport/symbols.c (_stp_do_relocation): Set new static_addr
_stp_section field.
* runtime/unwind.c (adjustStartLoc): Take new struct task_struct *tsk
argument and pass to stap_find_vma_map_info_user and _stp_module_relocate
to find adjusted addr.
(_stp_search_unwind_hdr): Pass through struct task_struct *tsk.
(unwind_frame): Likewise.
* tapset/context-symbols.stp (probemod): Add NULL to _stp_mod_sec_lookup
call to indicate we aren't interested in relative address.
* tapsets.cxx (dwarf_derived_probe_group::emit_module_init): Pass NULL to
_stp_module_relocate to indicate kernel/module address.

Several problems: some invalid <command> etc. directives
in the tapset embedded docs; some analysis about the
non-generation of the pdf; some cleanup of the generated
man pages.
* configure.ac (BUILD_PDFREFDOCS): Correct condition typo, but still
leave disabled.
* doc/SystemTap_Tapset_Reference/Makefile.am (XMLTOMANPARMS): Add,
to disable noise "AUTHORS" / "COPYRIGHT" sections.
* tapset/*.stp: Removed several docbook-y markup that is not valid
in kerneldoc.

* tapset/context-symbols.stp (syname, symdata): Pass NULL for kernel address.
* tapset/ucontext-symbols.stp: New file defining usymname and usymdata.
* testsuite/systemtap.context/usymbols.exp: Use usymname, remove
STP_NEED_VMA_TRACKER hack.
* testsuite/buildok/usymdata.stp: New test.
* testsuite/buildok/usymname.stp: Likewise.

This adds a couple of the suggested context/stack revamp functions
from PR6580. In particular it replaces the symbolname() function that
sneaked in with the pr6866 branch merge with the suggested symname().
* runtime/sym.c (_stp_mod_sec_lookup): Make section optional.
(_stp_symbol_snprint): Provide a way to get optional module info.
* tapset/context-symbols.stp: Replace symbolname() with symname(),
add modname() and symdata().
(probemod): Implement pc based fallback.
* tapset/context-unwind.stp (caller): Adjust for _stp_symbol_snprint
change.
* testsuite/systemtap.context/usymbols.exp: Use new symname.
* testsuite/buildok/modname.stp: New test.
* testsuite/buildok/symdata.stp: Likewise.
* testsuite/buildok/symname.stp: Likewise.
