Teach ir-ctl to send scancodes. This has a number of uses:
1. Controlling devices through IR transmission aka blasting
2. Testing the in-kernel software IR decoders (2 bugs uncovered so far)
3. Testing the capability of hardware IR decoders
All protocols supported by the kernel are supported except for XMP
and the MCE Keyboard.

+Rather than specifying the raw IR, you can also specify the scancode and
+protocol you want to send. This will also automatically set the correct
+carrier. The above can be written as:
+.PP
+ scancode rc5:0x1e01
+.PP
+Do not specify scancodes with different protocols in one file, as the
+carrier might differ and the transmitter cannot send this. Multiple
+scancodes can be specified in one file but ensure that the rules for the
+protocol are met by inserting an appropriate space between them. Also,
+there are limits to what lirc devices can send in one go.
+.PP
+.SS Supported Protocols
+A scancode with protocol can be specified on the command line or in the
+pulse and space file. The following protocols are supported:
+\fBrc5\fR, \fBrc5x\fR, \fBrc5_sz\fR, \fBjvc\fR, \fBsony12\fR, \fBsony\fB15\fR,
