Migration capabilities are closely related to migration parameters and
it makes sense to keep them in a single data structure. Similarly to
migration parameters the capabilities are all send to QEMU at once in
qemuMigrationParamsApply, all other APIs operate on the
qemuMigrationParams structure.

All users of migration parameters are supposed to use APIs provided by

The new name is qemuMigrationParamsApply and it will soon become the
only API which will send all requested migration parameters and
capabilities to QEMU. All other qemuMigrationParams* APIs will just
operate on the qemuMigrationParams structure.

There's no real reason for qemuMigrationParamsEnableTLS to require the
callers to pass a valid virQEMUDriverConfigPtr, it can just call
virQEMUDriverGetConfig.

The function checks whether QEMU supports TLS migration and stores the
original value of tls-creds parameter to priv->migTLSAlias. This is no
longer needed because we already have the original value stored in
priv->migParams.

Restore the original values of all migration parameters we store in
qemuDomainJobObj instead of explicitly resting only a limited set of
them.
The result is not strictly equivalent to the previous code wrt reseting
TLS state because the previous code would only reset it if we changed it
before while the new code will reset it always if QEMU supports TLS
migration. This is not a problem for the parameters themselves, but it
can cause spurious errors about missing TLS objects being logged at the
end of non-TLS migration. This issue will be fixed ~50 patches later.

Any job which touches migration parameters will first store their
original values (i.e., QEMU defaults) to qemuDomainJobObj to make it
easier to reset them back once the job finishes.

Currently migration parameters are stored in a structure which mimics
the QEMU migration parameters handled by query-migrate-parameters and
migrate-set-parameters. The new structure will become a libvirt's
abstraction on top of QEMU migration parameters, capabilities, and
related stuff.
