conf: add possibility to evaluate simple integer math expressions

2021-11-30T10:33:35+00:00

It is useful to use the math expressions for the values in configuration.
This patch adds a simple expression evaluation routines (integer only).
The syntax is simplified unix shell (bash) style.

Examples:

	$[1 + 1]
	$[$[2 + 2] / $var1]
	$[0xa0 | 0x05]

As a bonus, the variable substitutions were more abstracted.
The function snd_config_expand_custom() was introduced to be used
for example in the topology pre-precessor.
