This commit adds a new synthesis option to the design, that controls
whether an internal clock domain crossing will be generated. Disabling
this option allows you to use a synchronization signal that is
synchronized to the write clock domain externally, and possibly shared
between multiple devices.
The default value retains the old behavior.

This commit changes the transfer length register to work in increments of
64 bytes and without offset. The true transfer length can now be
determined by multiplying the value of the transfer_length register with
64.
A value of zero is interpreted as a request for all available storage.
Additionally, this commit fixes an off by one issue that was discovered
during testing of the RX path.
