094f29df07 Use virStringHasSuffix() where possible
When dealing with internal paths we don't need to worry about
whether or not suffixes are lowercase since we have full control
over them, which means we can avoid performing case-insensitive
string comparisons.

Despite its name, this is really just a general-purpose string

In addition to the obvious s/File/String/, also tweak the name
to make it clear that the presence of the suffix is verified

af36f8a641 Require a semicolon for VIR_ONCE_GLOBAL_INIT calls
Missing semicolon at the end of macros can confuse some analyzers
(like cppcheck <filename>). VIR_ONCE_GLOBAL_INIT is almost
exclusively called without an ending semicolon, but let's
standardize on using one like the other macros.

Add a dummy struct definition at the end of the macro, so
the compiler will require callers to add a semicolon.

5772885d28 lib: Use more of VIR_STEAL_PTR()
We have this very handy macro called VIR_STEAL_PTR() which steals
one pointer into the other and sets the other to NULL. The
following coccinelle patch was used to create this commit:

  @ rule1 @
  identifier a, b;
  @@

  - b = a;
    ...
  - a = NULL;
  + VIR_STEAL_PTR(b, a);

Some places were clean up afterwards to make syntax-check happy
(e.g. some curly braces were removed where the body become a one
liner).

e3a42028af Remove ignore_value or void from unlink calls
There seems to be no need to add the ignore_value wrapper or
caste with (void) to the unlink() calls, so let's just remove
them. I assume at one point in time Coverity complained. So,
let's just be consistent - those that care to check the return
status can and those that don't can just have the naked unlink.

10f94828ea virobject: Introduce VIR_CLASS_NEW() macro
So far we are repeating the following lines over and over:

  if (!(virSomeObjectClass = virClassNew(virClassForObject(),
                             "virSomeObject",
                             sizeof(virSomeObject),
                             virSomeObjectDispose)))
      return -1;

While this works, it is impossible to do some checking. Firstly,
the class name (the 2nd argument) doesn't match the name in the
code in all cases (the 3rd argument). Secondly, the current style
is needlessly verbose. This commit turns example into following:

  if (!(VIR_CLASS_NEW(virSomeObject,
                      virClassForObject)))
      return -1;

d04bc0278d secret: Fix memory leak in virSecretLoad
If the virSecretLoadValue fails, the code jumped to cleanup without
setting @ret = obj, thus calling virSecretObjListRemove which only
accounts for the object reference related to adding the object to
the list during virSecretObjListAdd, but does not account for the
reference to the object itself as the return of @ret would be NULL
so the caller wouldn't call virSecretObjEndAPI on the object recently
added thus reducing the refcnt to zero.

This patch will perform the ObjListRemove in the failure path of
virSecretLoadValue and Unref @obj in order to perform clean up
and return @obj as NULL. The @def will be freed as part of the
virObjectUnref.

13350a17e4 conf: Add new secret type "tls"
Add a new secret usage type known as "tls" - it will handle adding the
secret objects for various TLS objects that need to provide some sort
of passphrase in order to access the credentials.

The format is:

   <secret ephemeral='no' private='no'>
     <description>Sample TLS secret</description>
     <usage type='tls'>
       <name>mumblyfratz</name>
     </usage>
</secret>

Once defined and a passphrase set, future patches will allow the UUID
to be set in the qemu.conf file and thus used as a secret for various
TLS options such as a chardev serial TCP connection, a NBD client/server
connection, and migration.
