Minor code cleanups in pgbench expression support.

Browse Source 
Get rid of unnecessary expr_yylex declaration (we haven't supported
flex 2.5.4 in a long time, and even if we still did, the declaration in
pgbench.h makes this one unnecessary and inappropriate).  Fix copyright
dates, improve some layout choices, etc.
