  binutils/bfd: fix printf-like format strings for "bfd *" arguments

  There is a special format argument '%B' that directly handles values
  of type 'bfd *', they must be used instead of '%s'.  Manifestations
  of this bug can be seen in ld(1) error messages, for example,

MFC 272449:
Require p_cansched() for changing a process' protection status via
procctl() rather than p_cansee().
MFC 272668:
Properly set the timeout in a query_state.  The global query_timeout
configuration value is an integer count of seconds, it is not a timeval.
Using memcpy() to copy a timeval from it put garbage into the tv_usec
field.

MFC 268369,268817,272771,272772:
Rewrite timeout(9) to be callout(9)-centric instead.  Move the description
of timeout(9) to the end and mark it prominently as deprecated.  Document
somewhat how times are specified for the 'sbt' variants.  Better explain
how using callout_init_*() to associate a lock with a callout resolves
common races.
