Add update_table API: accepts sscanf style strings and populates a map
This is the culmination of the previous patches. It adds an api that can
input map data in a string format, but validating the numbers and
locations of data fields. The use case is for fuse file input/output. A
printf api may follow.
Take the table with key/leaf of:
struct Key { int a; int b; };
struct Leaf { int a; int b; int c; struct SubLeaf { int x; int y; } s; };
One would input to this table using:
update_table(table_name, "{1 2}", "{1 2 -3 {9 0xa}}");
The implementation uses a JITed function for each unique type, that is
invoked to run sscanf on behalf of the caller. The input must have the
exact right number of arguments. Bit fields are supported, but the
caller must be aware of the collapse of those bitfields into an aligned
field, as well as endianness.

Convert bpf_module structures to use vector instead of map for tables

Add pkg-config support and include compat/linux* in packaging
Different kernel header versions has been a continuing source of pain.
Though I don't prefer this approach, it seems the most reliable way to
get a build (for the time being) is to bundle the linux/bpf*.h in a
compat directory in the target install location.
To get visibility into that compat directory from another library, one
will need to rely on pkg-config --cflags argument to pull in that compat
directory.
Future work will be to avoid bundling the compat directory if the
version of linux-libc-dev is high enough, or if the presence of the
result of 'make headers_install' from the running kernel can be
detected.

Drop PROTO macro syntax and introduce alternative
* Feedback given by some external users was that the PROTO syntax was
opaque and unintuitive. As such, drop that macro and introduce an
alternative syntax.
* Convert all to use 'cursor_advance' macro API

Clean some brittle parts of clang rewriter

Clean some brittle parts of clang rewriter
* Rewrites of text inside of a macro (even if just the arguments) is not
support by clang. Convert macro definitions to pure rewrites instead.
* For packet field access, no longer require 'skb' named
argument...instead, learn it from the function parameter list.
* Add a complex test case...supposedly this should have failed issue
#10, but the C version does not exhibit the same failure as the B
version.
