Our existing protection only made sure that the first token in a
substitution wasn't a nested substitution. That's not sufficient when
there could be multiple tokens involved. This patch makes sure that no
nested tokens are ever allowed to be argument substitutions.
This also adds a cursor_suspended_line/column and resets the main
cursor_line/column to the beginning of the substitution, so errors will
point a little closer to the right place.

The components were being parsed for both target_symbols and cast_ops,
so this change refactors that code into a single function.
* parse.cxx (parser::parse_target_symbol_components): New.
(parser::parse_symbol): Use the new function.

The location already has a pointer to a stapfile with the filename, so
there's no need to keep an extra copy.

This speeds up the parsing stage >2x, mostly by minimizing string
construction and comparison where char comparison will do.

* translate.cxx: Added inclusion of session.h.
(translate_pass): Instead of asking each probe to emit itself, we
ask the session's probes member variable to emit all the probes.
* tapsets.cxx: Added inclusion of session.h. Added a
register_probe member function to all derived_probe based
classes. Added a derived_probe_group derived class for all probe
types:
(be_derived_probe_group): New class.
(never_derived_probe_group): New class.
(dwarf_derived_probe_group): New class.
(timer_derived_probe_group): New class.
(profile_derived_probe_group): New class.
(mark_derived_probe_group): New class.
(hrtimer_derived_probe_group): New class
(derived_probe_group_container): New class.
* elaborate.h: Removed inclusion of session.h since session.h now
includes elaborate.h.
(derived_probe): Added register_probe member function.
(derived_probe_group): Added class definition. This is the base
class of all of the derived probe groups - dwarf, timer, etc.
(derived_probe_group_container): Added class definition. An
instance of this class will be stored in the session and contain
all the other probe groups.
* elaborate.cxx (derived_probe_group::register_probe): Added
derived_probe_group::register_probe stubs.
(alias_derived_probe::register_probe): Added register_probe member
function.
(semantic_pass_symbols): After deriving a probe, the probes now
register themselves with the session.
* session.h: Includes elaborate.h to get
derived_probe_group_container definition. systemtap_session class
'probes' member variable switched from a vector of derived probes
to a derived_probe_group_container.
* buildrun.cxx: Added inclusion of session.h since it was removed

* parse.cxx (parser::parser): Added initializer for 'context'
member variable.
(tt2str): Added support for new tok_keyword type.
(operator <<): Ignores keyword content when outputting error
message.
(lexer::scan): Recognizes keywords, such as 'probe', 'global',
'function', etc. and classifies them as type 'tok_keyword'. This
causes keywords to become reserved so they cannot be used for
function names, variable names, etc.
(parser::parse): Changed tok_identifier to tok_keyword when looking
for "probe", "global", or "function". Also sets context member
variable which remembers if we're in probe, global, function, or
embedded context.
(parser::parse_probe, parser::parse_statement)
(parser::parse_global, parser::parse_functiondecl)
(parser::parse_if_statement, parser::parse_delete_statement)
(parser::parse_break_statement, parser::parse_continue_statement)
(parser::parse_for_loop, parser::parse_while_loop)
(parser::parse_foreach_loop, parser::parse_array_in): Looks for
tok_keyword instead of tok_identifier.
(parser::parse_probe_point): Allows keywords as part of a probe
name, since "return" and "function" are keywords.
(parser::parse_return_statement): Looks for tok_keyword instead of
tok_identifier. Make sure we're in function context.
(parser::parse_next_statement): Looks for tok_keyword instead of
tok_identifier. Make sure we're in probe context.
* parse.h: Added parse_context enum. Added 'tok_keyword' to
token_type enum. Added parse_context 'context' member variable to
parser class.
* stap.1.in: Because the string() function has been removed,
the 'string()' function reference has been changed to a 'sprint()'
function reference.
* stapex.5.in: Ditto.
* stapfuncs.5.in: The description of the string() and hexstring()
functions has been removed.

variable named 'string' was renamed to 'str'.
* testsuite/parseok/two.stp: Because keywords are reserved, a
variable named 'global' was renamed to 'gbl'.
* testsuite/transko/two.stp: Because the parser now checks for
'next' and 'return' statement context, a 'next' statement was
removed from a function and a 'return' statement was removed from
a probe.
