93a3a11d36 Merge remote-tracking branch 'origin/topic/vern/script-opt-keep-asserts' 
* origin/topic/vern/script-opt-keep-asserts:
  ZAM documentation updates for asserts and event handler run-time errors
  BTest updates for ZAM support of (optionally) keeping "assert" statements
  command-line options for controlling script optimization: keeping asserts, avoiding event handler coalescence
  ZAM support for option to not coalesce event handlers
  ZAM support for keeping "assert" statements
  internal support for script optimization options for keeping asserts, not consolidating event handlers
  ZAM operations to support asserts
  simplified "assert" by not trying to catch messages that themselves have errors

Fixed some TEST-REQUIRES "${ZEEK_ZAM}" == "1" to use "=" instead to
be /bin/sh compatible.

f5a76c1aed Reformat Zeek in Spicy style 
This largely copies over Spicy's `.clang-format` configuration file. The
one place where we deviate is header include order since Zeek depends on
headers being included in a certain order.
