maintenance fixes for variadic run-time checks, '_' placeholder identifier
"-O allow-cond" permits compiling scripts to C++ when influenced by @if conditionals
more robust standalone compile-to-C++ properties
fix for nested "when" statements
test suite updates
* Rename overly generic ACCESSORS macro with ZEEK_ prefix
* A few places where whitespace was noticeably wrong/distracting
* Minor/obvious reference/move semantics improvements suggested by linter
* Remove unused detail::Scope::Remove(), no need for deprecation
Merge adjustments:
- Preserved original `base_type_no_ref` argument type as ::TypeTag
- Removed superfluous #pragma guard around deprecated TableVal ctor
- Clarify NEWS regarding MetaHook{Pre,Post} deprecations
- Simplify some `::zeek::` qualifications to just `zeek::`
- Prefixed FORWARD_DECLARE_NAMESPACED macro with ZEEK_
* origin/topic/timw/266-namespaces:
Disable some deprecation diagnostics for GCC
Rename BroType to Type

Mark all of the aliased classes in plugin/Plugin.h deprecated, and fix all of the plugins that were using them
Move all of the base plugin classes into the zeek::plugin namespace
Expr: move all classes into zeek::detail
Stmt: move Stmt classes into zeek::detail namespace
Add utility macro for creating namespaced aliases for classes
* origin/topic/timw/nullptr:
The remaining nulls
plugin/probabilistic/zeekygen: Replace nulls with nullptr
file_analysis: Replace nulls with nullptr
analyzer: Replace nulls with nullptr
iosource/threading/input/logging: Replace nulls with nullptr
The big hitters:
Dict: Fills in four 4-byte holes in the structure. This shrinks Dictionary from 136 bytes to 114 bytes.
Desc: Fills in a 6-byte hole in the structure. This shrinks ODesc from 152 bytes to 144 bytes.
Frame: Moves and combines 4 bool variables from a few places into one single 4-byte block. This resolves all of the holes at once. This shrinks Frame from 216 bytes to 192 bytes and removes one cache line.
Func: Moves one int32_t variable to fill in a 4-byte hole. This shrinks Func from 112 bytes to 104 bytes.
ID: Moves two bool variables to fill in a 3-byte hole. This leaves behind a 1-byte hole, but removes a 6-byte pad from the end of the structure. This shrinks ID from 144 bytes to 136 bytes.
Other changes:
RuleHdrTest: Fills in one 4-byte hole in the structure. This shrinks RuleHdrTest from 248 bytes to 240 bytes.
RuleEndpointState: Moves one bool variable down in the structure to reduce a 7-byte hole. This unfortunately causes a 3-byte hole later in the structure but there’s no easy way to filll it in. This does shrink RuleEndpointState from 128 bytes to 120 bytes though.
ScannedFile: Moves two bool values to reduce a 4-byte hole by 2 bytes. This shrinks ScannedFile from 64 bytes to 56 bytes.
Brofiler: Moves one char value to reduce a 4-byte hole by 1 byte. This shrinks Brofiler from 96 bytes to 88 bytes and removes one cache line.
DbgBreakpoint: Moves some values around to fill in a 4-byte hole and reduce a second. A 2-byte hole still exists, but the structure shrinks from 632 bytes to 624 bytes. It’s possible on this one that one of the int32_t values could be an int16_t and remove the last 2-byte gap.
ParseLocationRec: Moves one int to fill in a 4-byte hole. This shrinks ParseLocationRec from 32 bytes to 24 bytes.
DebugCmdInfo: Moves one bool variable to shift a few others up. This results in a 6-byte pad at the end of the structure but removes a 7-byte hole in the middle. This shrinks DebugCmdInfo from 56 bytes to 48 bytes.
FragReassembler: Moves one variable down to fill in a 4-byte hole. This shrinks FragReassembler from 272 bytes to 264 bytes.
nb_dns_result: Moves ones uint32_t variable to fill in a 4-byte hole, also removing a 4-byte pad from the end of the structure. This shrinks nb_dns_result from 32 bytes to 24 bytes.
nb_dns_entry: Moves one short value to fill in a 2-byte hole, also removing a 6-byte hole. This shrinks nb_dns_entry from 1064 bytes to 1056 bytes.
