The previous commit 18effad9cfa7 ("stack: reload head when pop fails")
only changed C11 implementation, not generic implementation.
List head must be loaded right before continue (when failed to find the
new head). Without this, one thread might keep trying and failing to pop
items without ever loading the new correct head.

When VM size is larger than 4G (u32) and memory region is larger than 4G,
the 32-bit GCD function overflowed and returned wrong value
that resulted in memory registration failure.
This patch calls 64-bit GCD function to avoid overflow.

Generate a C function for each custom instruction, which essentially
consolidate multiple regular instructions into a single function call.
The pipeline program is split into groups of instructions, and a
custom instruction is generated for each group that has more than one
instruction. Special care is taken the instructions that can do thread
yield (RX, extern) and for those that can change the instruction
pointer (TX, near/far jump).

For better performance, the option to run a single function per action

can be better optimized by the C compiler, as opposed to one function

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.
