Names of firmware configuration files always take 56 bytes (including at
least one terminating NUL byte). Expose this constant to all consumers of
QemuFwCfgLib because further interfaces may depend on it.

This internal function allows separation of library-internal and
for-clients external availability of fw_cfg.
The interface contract of QemuFwCfgIsAvailable() is changed so that now it
may modify fw_cfg state. All current users are compliant with the new
contract.

Tested with the "bootorder" fw_cfg file. Example contents (leading space
added and line terminators transcribed for readability):
/pci@i0cf8/ide@1,1/drive@0/disk@0<LF>
/pci@i0cf8/ide@1,1/drive@1/disk@0<LF>
/pci@i0cf8/ethernet@3/ethernet-phy@0<NUL>
