4707331d15 qapi: Document QCryptodevBackendServiceType
QCryptodevBackendServiceType was introduced by
bc304a6442 (cryptodev: Introduce server type in QAPI). However there
is a lack of member description.

b1019999e8 qapi/cryptodev: Rename QCryptodevBackendAlgType to *Algo, and drop prefix
QAPI's 'prefix' feature can make the connection between enumeration
type and its constants less than obvious.  It's best used with
restraint.

QCryptodevBackendAlgType has a 'prefix' that overrides the generated
enumeration constants' prefix to QCRYPTODEV_BACKEND_ALG.

We could simply drop 'prefix', but I think the abbreviation "alg" is
less than clear.

Additionally rename the type to QCryptodevBackendAlgoType.  The prefix
becomes QCRYPTODEV_BACKEND_ALGO_TYPE.

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()

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]

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

See recent commit "qapi: Relax doc string @name: description

Reflow paragraphs to 70 columns width, and consistently use two spaces
to separate sentences.

To check the generated documentation does not change, I compared the
generated HTML before and after this commit with "wdiff -3".  Finds no
differences.  Comparing with diff is not useful, as the reflown

4622c70689 qapi storage-daemon/qapi: Fix documentation section structure
In the QEMU QMP Reference Manual, subsection "Block core (VM
unrelated)" is empty.  Its contents is at the end of subsection
"Background jobs" instead.  That's because qapi/job.json is included
first from qapi/block-core.json, which makes qapi/job.json's
documentation go between qapi/block-core.json's subsection heading and
contents.

In the QEMU Storage Daemon QMP Reference Manual, section "Block
Devices" contains nothing but an empty subsection "Block core (VM
unrelated)".  The latter's contents is at the end section "Socket data
types", along with subsection "Block device exports".  Subsection
"Background jobs" is at the end of section "Cryptography".  All this
is because storage-daemon/qapi/qapi-schema.json includes modules in a
confused order.

Fix both as follows.

Turn subsection "Background jobs" into a section.

Move it before section "Block devices" in the QEMU QMP Reference
Manual, by including qapi/jobs.json right before qapi/block.json.

Reorder include directives in storage-daemon/qapi/qapi-schema.json to
match the order in qapi/qapi-schema.json, so that the QEMU Storage
Daemon QMP Reference Manual's section structure the QEMU QMP Reference
Manual's.

In the QEMU QMP Reference Manual, qapi/cryptodev.json's documentation
is at the end of section "Virtio devices".  That's because it lacks a
section heading, and therefore gets squashed into whatever section
happens to precede it.

Add section heading so it's in section "Cryptography devices".

Then we can keep 'CRYPTODEV_BACKEND_ALG_SYM' and avoid lots of
