* terminal.bbclass: Improve environment handlingRichard Purdie2011-09-091-7/+6
| | | | | | | | | | | | | | | | | Currently the environment handling for terminals is inconsistent. There are two fixes here: a) Ensure the environment is setup before all oe.terminal call b) Actually set the environment before the spawn calls since we need variables like DISPLAY when the commands are being executed, not just within the terminal environment. If this doesn't happen, DISPLAY can end up not set with the errors that brings with it when trying to run X commands.

In the new implementation, each known terminal is defined as a class in oe.terminal, as a subclass of bb.process.Popen. terminal.bbclass wraps this functionality, providing the metadata pieces. It obeys the OE_TERMINAL variable, which is a 'choice' typed variable. This variable may be 'auto', 'none', or any of the names of the defined terminals. When using 'auto', or requesting an unsupported terminal, we attempt to spawn them in priority order until we get one that's available on this system (and in the case of the X terminals, has DISPLAY defined). The 'none' value is used when we're doing things like automated builds, and want to ensure that no terminal is *ever* spawned, under any circumstances.
