2b96db5fac Do not share constant 1 for enum autoincrements.
- AST nodes cannot be shared, because type conversion changes them in
  place, and what's appropriate for one use is by no means appropriate for
  all uses.

6384613487 Allow using constants in other constants before their definitions.
- Something like this is now valid:
    const foo = bar + 10;
    const bar = 1000;

76d2e8cfc4 Set node type when nil-ing an id node.
- Nodes can't stay as type AST_ExprID if they don't also have the
  operation PEX_ID.

850055a766 Add evaluation of constant unary and binary expressions
- Added ZCCCompiler class as a place to generate IR and symbols from an
  AST. Right now, all it does is simplify constant expressions into
  constant values.
- Do type promotion on the AST where appropriate.
- Added true and false tokens to the parser driver.

c7e817dfb9 Added type conversion search routines
- PType::FindConversion() can find a path to convert one type to another.
  This is completely generic and can handle any number of conversion
  functions.

4bd5bf310b Do not use GT, GTEQ, or NEQ operators in the AST.
- Since the VM doesn't directly support the GT, GTEQ, and NEQ comparisons,
  don't use them in the trees either. Instead, wrap them as LTEQ, LT, and
  EQEQ inside a BoolNot operator.

a0dbcb5d5b Add TRUE and FALSE terminals to the zcc grammar
- I can't believe I completely forgot to let the parser handle true and
  false literals.
- Consolidate all the %include blocks in zcc-parse.lemon into a single
  one, because Lemon all of a sudden decided it didn't like me having more
  than one in the grammar file.
- Added a PBool type to represent boolean values with.

1948642758 Add Printf extension %H
- This conversion has behavior similar to %g: It automatically behaves like
  %f or %e based on the number of output characters. However, unlike %g,
  this decision is also based on what will produce the smallest string
  without truncating the output. The precision field (the * in %.*f) is
  ignored. Converting a double to text with %H and then back to a double
  should be lossless.

0fb9f98a96 Add void and error types; rejigger pointer types
- Added TypeVoid for statements, which produce no type.
- Added TypeError for expressions whose arguments are incompatible.
- Pointers now derive from PBasicType instead of PInt. Since they have their own register sets in the VM, this seems to make more sense than treating them as integers.

743b05189e Give the parser knowledge of constants for unary - and +
- Since the tokenizer never gives the parser negative numbers but always a
  unary minus followed by a positive number, it seems reasonable to make
  the parser smart enough to turn these into negative constants without
  generating extra tree nodes.
- And since we're doing it for unary -, we might as well do it for unary +
  as well and avoid extra nodes when we know we don't need them.

2a1414ad66 Use labels in autogenerated enum value expressions
- For an enum like this:
    enum { value1 = SOME_NUM*2, value2 };
  Generate an increment expression for value2 of the form
    (add (id value1) 1)
  and not
    (add (* SOME_NUM 2) 1)

af8e0f2ba6 Represent enumerations as constant definitions
- Instead of representating enumeration values with a special node type,
  use the same ZCC_ConstantDef nodes that const_def produces. These are
  created at the same scope as the ZCC_Enum, rather than being contained
  entirely within it. To mark the end of enums for a single instance of
  ZCC_Enum, a ZCC_EnumTerminator node is now appended to the chain of
  ZCC_ConstantDefs.

d5fa550118 Make ZCC_TreeNode::AppendSibling() work with lists
- Previously, you could only append lone nodes to ZCC_TreeNode lists.
  Now you can append one list to another.

2ab3974752 Add a PSymbolConstString class
- Constants can be strings, but the existing PSymbolConst couldn't handle
  them. The old PSymbolConst is now PSymbolConstNumeric, and the new
  PSymbolConst is a now a baseclass for it and PSymbolConstString.

3044fdd0a9 Use %f instead of %g in AST dumps

  point, FLispString::AddFloat() now prints them with %f.

61666e1515 Consolidate constant expression nodes into a single type
- Instead of having ZCC_ExprString, ZCC_ExprInt, and ZCC_ExprFloat,
  just use a single ZCC_ExprConstant. It should simplify type
  promotion and constant folding in the future.

f9f8d1e79b Add a type field for ZCC expressions.
- Constants can fill out the type field right away. Other expressions will need
  to wait until a later pass, after names have been resolved, so they get
  initialized to NULL.

260ce62175 Don't abort for TEXTUREx lumps that define textures with no patches
- A texture defined in TEXTUREx without any patches isn't necessarily an
  error, so accept. This also means they shouldn't be used for determining
  if a TEXTURE directory belongs to Strife instead of Doom.

b0371e1804 Don't abort when merely checking if a non-map is a map
- When P_OpenMapData() is called by P_CheckMapData(), we don't actually
  care if any required lumps are missing. This just means it isn't a valid
  map, so don't abort with I_Error().

0f0d9da839 Reset FirstFreeEntry in ACSStringPool::ReadStrings()
- Fixed: When an ACS string pool was read from a savegame, FirstFreeEntry
  would not be updatedt, except by the Clear() function. This left FirstFreeEntry
  at 0, which meant the next string added to the pool would always go in
  slot 0, whether it was free or not.

7143ae49e1 Fixed: CheckPlayerCamera not sync safe
-  If a player is spying through another player, CheckPlayerCamera will
   return the TID of the player you are "spying", but as coopspy isn't a
   net command, this wont be reflected by all nodes. So to fix this,
   CheckPlayerCamera now returns -1 if a player's camera is that of any
   player at all. (thanks edward850)

28e5cc536a Add some awareness of short file names
- Added I_GetLongPathName(). It wraps the Win32 API's GetLongPathName().
  DArgs::CollectFiles() now calls this for every argument it processes, so
  any arguments passed using short file names will be converted to long
  file names. This is mainly of interest so that savegames will never
  record the short file name, which can change based on what else is in
  the directory.
