The QAPI code generator clocks in at some 3100 SLOC in 8 source files. Almost 60% of the code is in qapi/common.py. Split it into more focused modules: * Move QAPISchemaPragma and QAPISourceInfo to qapi/source.py. * Move QAPIError and its sub-classes to qapi/error.py. * Move QAPISchemaParser and QAPIDoc to parser.py. Use the opportunity to put QAPISchemaParser first. * Move check_expr() & friends to qapi/expr.py. Use the opportunity to put the code into a more sensible order. * Move QAPISchema & friends to qapi/schema.py * Move QAPIGen and its sub-classes, ifcontext, QAPISchemaModularCVisitor, and QAPISchemaModularCVisitor to qapi/gen.py * Delete camel_case(), it's unused since commit e98859a9b9 "qapi: Clean up after recent conversions to QAPISchemaVisitor" A number of helper functions remain in qapi/common.py. I considered moving the code generator helpers to qapi/gen.py, but decided not to. Perhaps we should rewrite them as methods of QAPIGen some day.
