Drivers will start outputting this as a hardware ID packet in the data

To prepare for this we provide a helper functions to do the individual ID

'j' is of type int and start/end are of type 'long'. Thus 'j' might become
negative and cause segfault in access_data(). Fix it by using 'long' for
'j' as well.

When a build is done without DEBUG=1 then define NDEBUG. This will
compile out asserts and other debug code.

With NDEBUG set the asserts are compiled out. This yields
"unused-but-set-variable" variables. Move these variables behind
NDEBUG to avoid the warning.

Allow addr2line to be set either on the command line or via the
perfconfig file. This doesn't currently work with llvm-addr2line as
the addr2line code emits two things:
1) the address to decode,
2) a bogus ',' value.
The expectation is the bogus value will generate:
??
??:0
that terminates the addr2line reading. However, the output from
llvm-addr2line is a single line with just the input ',' locking up the
addr2line reading that is expecting a second line.

Make struct annotation_options own the strings objdump_path and
disassembler_style, freeing them on exit. Add missing strdup for
disassembler_style when read from a config file.
Committer notes:
Converted free(obj->member) to zfree(&obj->member) in
annotation_options__exit()

The annotation__default_options global variable was used to initialize
annotation_options. Switch to the init/exit pattern as later changes
will give ownership over strings and this will be necessary to avoid
memory leaks.
Committer note:
Fix the GTK2=1 build, hist_entry__gtk_annotate() needs to receive a
'struct annotation_options' pointer.
