Wade Fife 287659ddeb fpga: Fix first arg in calls to $fatal()
This fixes warnings regarding the first argument to $fatal(), which is
supposed to be a number indicating what diagnostics to display. 1
corresponds to "Prints simulation time and location".

Andrew Moch 23be04661f fpga: lib: Add synthesizable AXI4-Stream SV components
Components are connected together with AxiStreamIfc. Some features
include:
  (1) Add bytes to the start of a packet
  (2) Remove bytes from a packet
  (3) Wrappers for some older components
      a.  fifo - buffer but imediately pass a packet
      b.  packet_gate - buffer and hold till end of packet
      c.  width_conv - cross clock domains and change width of axi bus

The AxiStreamIf was moved from PkgAxiStreamBfm to its own file. It can
be used to connect to ports with continuous assignment.
AxiStreamPacketIf must be used procedurally but allows the following
new methods:
  - reached_packet_byte - notify when tdata contains a paritcular byte
  - get_packet_byte/get_packet_field - extract a byte or field from axi
  - put_packet_byte/put_packet_field - overwrite a byte or field onto axi
