Lay the foundation to generate C code for the pipeline: C functions
for actions and custom instructions are generated, built as shared
object library and loaded into the pipeline.

For better performance, the option to create custom instructions when
the program is translated and add them on-the-fly to the pipeline is
now provided. Multiple regular instructions can now be consolidated
into a single C function optimized by the C compiler directly.

For better performance, the option to run a single function per action
is now provided, which requires a single function call per action that
can be better optimized by the C compiler, as opposed to one function
call per instruction. Special table lookup instructions are added to
to support this feature.

A learner table is typically used for learning or connection tracking,
where it allows for the implementation of the "add on miss" scenario:
whenever the lookup key is not found in the table (lookup miss), the
data plane can decide to add this key to the table with a given action
with no control plane intervention. Likewise, the table keys expire
based on a configurable timeout and are automatically deleted from the
table with no control plane intervention.

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.

The RTE_ALIGN macro is aligned upwards. If the buf_size variable is not
aligned with 1 << I40E_RXQ_CTX_DBUFF_SHIFT, the rx_buf_len is larger than
the actual mbuf memory after the operation. When receiving the packet, if
the packet is larger than the configured buf_size, it will cause a memory
stepping event.
The patch uses the RTE_ALIGN_FLOOR down alignment macro to correct the
problem.
