Detailed Description

A class for sarif_objects that own a "namespace" of numeric IDs for
 managing location objects within them.  Currently (SARIF v2.1.0)
 this is just for sarif_result (section 3.28.2), but it will likely
 eventually also be for notification objects; see
 https://github.com/oasis-tcs/sarif-spec/issues/540

 Consider locations with chains of include information e.g.

 > include-chain-1.c:
 >   #include "include-chain-1.h"

 include-chain-1.h:
   | // First set of decls, which will be referenced in notes
   | #include "include-chain-1-1.h"
   |
   | // Second set of decls, which will trigger the errors
   | #include "include-chain-1-2.h"

 include-chain-1-1.h:
   | int p;
   | int q;

 include-chain-1-1.h:
   | char p;
   | char q;

 GCC's textual output emits:
   |   In file included from PATH/include-chain-1.h:5,
   |                    from PATH/include-chain-1.c:30:
   |   PATH/include-chain-1-2.h:1:6: error: conflicting types for 'p'; have 'char'
   |       1 | char p;
   |         |      ^
   |   In file included from PATH/include-chain-1.h:2:
   |   PATH/include-chain-1-1.h:1:5: note: previous declaration of 'p' with type 'int'
   |       1 | int p;
   |         |     ^
   |   PATH/include-chain-1-2.h:2:6: error: conflicting types for 'q'; have 'char'
   |       2 | char q;
   |         |      ^
   |   PATH/include-chain-1-1.h:2:5: note: previous declaration of 'q' with type 'int'
   |       2 | int q;
   |         |     ^

 Whenever a SARIF location is added for a location_t that
 was #included from somewhere, we queue up the creation of a SARIF
 location for the location of the #include.  The worklist of queued
 locations is flushed when the result is finished, which lazily creates
 any additional related locations for the include chain, and the
 relationships between the locations.  Doing so can lead to further
 include locations being processed.  The worklist approach allows us
 to lazily explore the relevant part of the directed graph of location_t
 values implicit in our line_maps structure, replicating it as a directed
 graph of SARIF locations within the SARIF result object, like this:

 [0]: error in include-chain-1-2.h ("conflicting types for 'p'; have 'char'")
 [1]: #include "include-chain-1-2.h" in include-chain-1.h
 [2]: note in include-chain-1-2.h ("previous declaration of 'p' with type 'int'")
 [3]: #include "include-chain-1-1.h" in include-chain-1.h
 [4]: #include "include-chain-1.h" in include-chain-1.c

 where we want to capture this "includes" graph in SARIF form:
 . +-----------------------------------+ +----------------------------------+

 . | error: "conflicting types for 'p';| | note: previous declaration of 'p'|
 . |  have 'char'"|                    | | with type 'int'")                |
