c1905c2169 Halt assembly if addresses are not converging.
Change global_offset_changed from bool to int so that
progress of convergence can be monitored. If change count
does not decrease from previous pass, increment stall counter.
If stall count reaches threshold, terminate assembly
with error message.

cd3418016a Remove EQU for critical expression list
Allow redefine_label to update segment as well as offset,
thereby fixing bug which required EQU to be on the
critical expression list.

166c247f36 hash user allocates struct hash_table
struct hash_table, a fixed-sized structure, is now allocated by the
caller.  This lets us integrate it into the Context structure, thus
avoiding an additional dynamically allocated object for no good
reason.

Add some minor code collapsing: make it more obvious that all that
differs is a pointer value, rather than relying on the compiler to do
tail merging.

072771e4a5 Use hash tables even for context-sensitive macros
Normally, contexts aren't used with a large number of macros, but in
case someone does, do use hash tables for those as well.  This
simplifies the code somewhat, since *all* handling of macros is now
done via hash tables.

Future note: consider if it wouldn't be better to allow struct
hash_table to be allocated by the caller, instead of being allocated
by the hash table routine.

d60059ef41 Display fully qualified local label in "not defined" message
Add new function "local_scope" to label subsystem to
return the previous non-local label for a given local label,
and invoke this funcion in eval.c to display the fully
qualified name in the "not defined" error message.

7065309739 Formatting: kill off "stealth whitespace"
"Stealth whitespace" makes it harder to read diffs, and just generally
cause unwanted weirdness.  Do a source-wide pass to get rid of it.

70055964fc Additional uses of bool and enum
Proper use of bool and enum makes code easier to debug.  Do more of
it.  In particular, we really should stomp out any residual uses of
magic constants that aren't enums or, in some cases, even #defines.

6867acc18e Use the compiler-provided booleans if available, otherwise emulate
Both C and C++ have "bool", "true" and "false" in lower case; C
requires <stdbool.h> for this, in C++ it is an inherent type built
into the compiler.  Use those instead of the old macros; emulate with
a simple typedef enum if unavailable.

fe501957c0 Portability fixes
Concentrate compiler dependencies to compiler.h; make sure compiler.h
is included first in every .c file (since some prototypes may depend
on the presence of feature request macros.)

Actually use the conditional inclusion of various functions (totally
broken in previous releases.)

97a234782d Switch the preprocessor over to using the hash table library
Switch the preprocessor over to using the hash table library.  On my
system, this improves the runtime of the output of test/pref/macro.pl
from over 600 seconds to 7 seconds.

Macros have an odd mix of case-sensitive and case-insensitive
behaviour, plus there are matching parameters for arguments, etc.  As
a result, we use case-insensitive hash tables and use a linked list to
store all the possible isomorphs.

d2fb7a699e Fix the handling of local labels
In converting the label system over to the new hash table library,
accidentally broke local labels by prepending the prefix twice.  Fix.

6244f4b5b9 Use the new hash table function library to store labels
Use the new hash table function library to store labels.  When
compiling on my 64-bit system, it reduces the assembly time for the
output of test/perf/label.pl from 73 to 7 seconds.
