[opentitantool] Persistent session support
This change introduces a `opentitansession` command.
`opentitansession --conf ... --interface ...` will start a new
persistent session process, which would load the given configuration
files and connect to the given physical interface.
Default transport in absense of `--interface` has been changed to be
"proxy" on `localhost:9900`, such that manual one-off manipulation
can be done with the shortest possible command line.
Configuration files are loaded as part of the session process startup,
meaning that aliases can be used in the `gpio read` command above,
without each individual invocation needing `--conf ...`.
Forwarding of GPIO, UART and SPI has been verified with UltraDebug and
Andreiboard: `opentitantool bootstrap` and `opentitantool console`
works.
Simulation transports such as Verilator or Ti50 host emulation would
create a simulation environment as part of the constructor for their
implementation of the `Transport` trait.
Large parts of the asynchronous socket code has been copied from host
emulation code in the Ti50 repository, developed by Semihalf.
For now, the session process will continue running in the foreground,
(unless shell primitives are used). A followup will enable proper
daemon functionality, with .pid files, etc.
