:common is redundant. Remove.

common is not the only target in that gn, why it is redundant?

[please use gerrit instead, 2017/04/06 14:35:28]

"//components/webdata/common:common" is equivalent to
"//components/webdata/common". So ":common" is not adding any more information,
it only slows down whoever is reading this file.

[gogerald1, 2017/04/06 16:42:09]

common is the default target of //components/webdata/common, then make it
explicit would be better?

Anyway, addressed it as you commented, saw various preference in gn, but mostly
use implicit target name

     "//net",

:sql is redundant. Remove.
