Markus Armbruster 7b29353fdd qapi: Smarter camel_to_upper() to reduce need for 'prefix'
camel_to_upper() converts its argument from camel case to upper case
with '_' between words.  Used for generated enumeration constant
prefixes.

When some of the words are spelled all caps, where exactly to insert
'_' is guesswork.  camel_to_upper()'s guesses are bad enough in places
to make people override them with a 'prefix' in the schema.

Rewrite it to guess better:

1. Insert '_' after a non-upper case character followed by an upper
   case character:

       OneTwo -> ONE_TWO
       One2Three -> ONE2_THREE

2. Insert '_' before the last upper case character followed by a
   non-upper case character:

       ACRONYMWord -> ACRONYM_Word

   Except at the beginning (as in OneTwo above), or when there is
   already one:

       AbCd -> AB_CD

This changes the default enumeration constant prefix for a number of
enums.  Generated enumeration constants change only where the default
is not overridden with 'prefix'.

The following enumerations without a 'prefix' change:

    enum                            old camel_to_upper()
                                    new camel_to_upper()

                                    TEST_UNION_ENUM_A

Add a 'prefix' so generated code doesn't change now.  Subsequent
commits will remove most of them again.  Two will remain:
MULTIFD_COMPRESSION, because migration code generally spells "multifd"
that way, and Q_KEY_CODE, because that one is baked into
subprojects/keycodemapdb/tools/keymap-gen.

The following enumerations with a 'prefix' change so that the prefix
is now superfluous:

    enum                            old camel_to_upper()
                                    new camel_to_upper() [equal to prefix]

                                    QTYPE

Drop these prefixes.

Subsequent commits will tweak things to remove most of these prefixes.
Only QAUTHZ_LIST_FORMAT and QAUTHZ_LIST_POLICY will remain.
