multi reader fifos

Special kind of fifos where any number of producers and readers may be "connected". This fifos provides the following features:
 * Transfers are done in indivisible blocks of contiguous data
 * Read/Write operations are done in packets of one or more blocks
 * Blocks may be read/written in between of others, even in one write operation
 * Blocks always arrive in order (even if not contiguous because of preceding point)

{{{
fifo1 = Memr("first_fifo",
             4, # Width, in 32-bit words, this is block size
             64) # Depth, in number of blocks
}}}

== Lock ==

Simple mutex, implemented through [wiki:SpinLock spin locks].

{{{
lock1 = Lock("first_lock")
}}}

== Barrier ==

Synchronization point between tasks. All tasks connected to a barrier must wait for it before going any further.

{{{
barr = Barrier("sync")
}}}

== Memspace ==

Shared (or not) memory declaration, may be used to have global memory space shared between tasks.

{{{
memsp = Memspace("mem_name", 32768)
}}}

== Const ==

Constant integer values.

{{{
cex = Const(1)
}}}
