signal.7: Place signal numbers in a separate table 

The current tables of signal information are unwieldy,
as they try to cram in too much information.

.SS Signal numbering for standard signals
The numeric value for each signal is given in the table below.
As shown in the table, many signals have different numeric values
on different architectures.
The first numeric value in each table row shows the signal number
on x86, ARM, and most other architectures;
the second value is for Alpha and SPARC; the third is for MIPS;
and the last is for PARISC.
A dash (\-) denotes that a signal is absent on the corresponding architecture.
