strings: Introduce the strings class
...
And make the dwarves use it, so that we can remove duplicate strings in
a multi-CU file (vmlinux anyone?) and have it ready for insertion in a
compressed DWARF format with just the types, or better, CTF or some new
compressed debugging info format.

To indicate wheter the semicolon should be supressed. Useful for
prototype/function emission, etc.
Also move the struct stats to be inside its body, to simplify tag__fprintf,
that now looks at conf.no_semicolon after calling the tag type specific
__fprintf method.

[LIB]: Use a base_offset when printing inner structs
...
That way we can have the offsets from the top level struct. If the user wants
to focus some inner struct, just call the tool again specifying the inner
struct name.
Perhaps this is not so clear, shoot me, erm, no, an example should help. Look
at the member offsets (first column in the comment after each member), before
and after:
before:
acme@filo pahole]$ pahole -C tcp_sock --expand_types examples/net

struct sock {

Quick hack, as we already had all the needed infrastructure due to anonymous struct
printing inside structs/unions, now for the curious, if you have the kernel-debuginfo
package installed in your FC6 machine:
[acme@filo pahole]$ pahole --expand_types /usr/lib/debug/lib/modules/2.6.19-1.2895.fc6/kernel/net/ipv6/ipv6.ko.debug tcp6_sock
Try struct task_struct too 8-)
