Escape literal '.'s in regular expressions
* dwflpp.cxx (dwflpp::build_blacklist): Escape '.'s in filenames.
commit 178ac3f6fdef839ef1ca646421e2c436a91ac1fb

Use a regexp for matching blacklist sections
We already use regexp for function/file blacklisting, so this just makes
the section blacklisting consistent with the rest.
* dwflpp.cxx (dwflpp::blacklisted_p): Use regexec instead of section==.
(dwflpp::build_blacklist): Build blacklist_section too.

Author: Josh Stone <jistone@redhat.com>
Date: Thu Sep 3 12:00:10 2009 -0700
Fetch the blacklist section only when needed
We only check blacklisting on kernel probes, so it's a waste to dig up
the section name otherwise.
* dwflpp.cxx (dwflpp::blacklisted_p): Lookup the section directly.
(relocate_address::relocate_address): Don't do blacklisting here.
* tapsets.cxx (dwarf_query::add_probe_point): Don't carry the blacklist
section directly anymore.

PR10573: Squash duplicate inline instances
In C++, identical functions included in multiple CUs will get merged at
link time into a single instance. We need to make sure that inlines
within those merged functions are not probed multiple times.
* tapsets.cxx (inline_instance_info::operator<): Used for set support.
(dwarf_query::handle_query_module): Clear inline_dupes on each module.
(query_dwarf_inline_instance): Squash this inline instance if it's
already in the inline_dupes set.

PR10572: Allow duplicate function names in a CU
We can't assume that a given function name will only appear once in a
CU. In C++, two functions may have the same name in different classes
or namespaces, or even in the same scope with overloaded parameters.
Even in C, the compiler may generate multiple copies of a single
function with different optimizations.
We now use a multimap for function names, so we shouldn't miss any.
* dwflpp.h (cu_type_cache_t, mod_cu_type_cache_t): New typedef to keep a
normal map for the global_alias_cache.
(cu_function_cache_t): Use a multimap for function names.
* dwflpp.cxx (dwflpp::iterate_over_functions): Walk over the range of
exactly-matching functions.
* tapsets.cxx (query_dwarf_func): Don't abort after seeing an exact
match -- there could be more to come.

Delete stuff that dwflpp newed
* dwflpp.cxx (dwflpp::~dwflpp): Delete all of the caches.

Provide backward-compatible unordered_map/set
We were defining our own stap_map with a ::type to let us use typedefs
to use the new unordered_map if available, or hash_map otherwise. Since
unordered_map is the future direction, I'm changing our code to use that
directly. The backward-compatible version is a #define to hash_map,
which has a compatible interface.
While I'm at it, let's also define unordered_multimap, unordered_set,
and unordered_multiset.
* unordered.h: New.
* dwflpp.h (stap_map): Removed.
(cache typedefs): Use the unordered name now.

Unify lex_cast* and avoid string copies
We always use lex_cast either to string or from string, so I made that
explicit, and got rid of some string copies in the process. There was
also stringify(), which was redundant to lex_cast<string>.
We also always used lex_cast_hex to string, so that's now hard-coded and
again eliminated a string copy.
For lex_cast_qstring<string>, there's no need to write the streamify the
input, so a specialization now operates directly on the input.
Hopefully this is a bit cleaner, and I do measure it to be a little
faster on scripts with many probes.
