Add .library("lib").mark("mark") and use it for .mark semaphores.
tapset-utrace.cxx (TOK_LIBRARY): New.
(utrace_derived_probe::utrace_derived_probe): Add library and has_library.
(utrace_builder::build): Handle library.
(utrace_derived_probe_group::emit_probe_decl): Add sdt_sem_offset to
emitted stap_utrace_probes. Add stap_task_finder_target
mmap_callback for handling shared library. Handle sdt_sem_offset in
emitted_stp_utrace_probe_cb. Add stap_utrace_mmap_found.
(register_tapset_utrace): Handle .library

(base_query::base_query): Add path and has_library.
(dwarf_derived_probe::dwarf_derived_probe) Likewise.
(dwarf_derived_probe::register_patterns): Handle .library
(sdt_query::convert_location): Likewise.
(dwarf_builder::build): Likewise.
(uprobe_derived_probe_group::emit_module_decls): Emit
sdt_sem_address. Add sdt_sem_offset to emitted stap_uprobe_spec.
Add offset and vm_flags to signature of stap_uprobe_change_plus, and
handle sdt_sem_offset. Allow writeable segments in emitted
stap_uprobe_mmap_found.
sdt_misc.exp: Test .library
util.cxx (find_executable): Add env_path to sig and use it in getenv.
util.h (find_executable): Likewise. Make "PATH" the default.
