Start to consolidate the data structures and inline functions required
by the pipeline instructions into an internal header file.

Added look-ahead instruction to read a header from the input packet
without advancing the extraction pointer. This is typically used in
correlation with the special extract instruction to extract variable
size headers from the input packet: the first few header fields are
read without advancing the extraction pointer, just enough to detect
the actual length of the header (e.g. IPv4 IHL field); then the full
header is extracted.

Added a mechanism to extract variable size headers through a special
flavor of the extract instruction. The length of the last struct field
which has variable size is passed as argument to the instruction.

Added support for variable size headers. The last field of a struct
type can now have a variable size between 0 and N bytes. Useful to
accommodate IPv4 packets with options, etc.

The emit instruction that is responsible for pushing headers into the
output packet is now reading the header length from internal run-time
structures as opposed to constant value from the instruction opcode.

This patch fixes the memcpy function call which was incorrect and led
to memory corruption for tables with more that just a few actions.

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
