[libvirt] [PATCH v1 03/40] util: buffer: typedef and Free helper for struct _virBufferEscapePair

[Sukrit Bhatnagar]

Create typedefs virBufferEscapePair and virBufferEscapePairPtr
for struct _virBufferEscapePair for cleaner code and for use
with cleanup macros.

Also create a dedicated Free helper virBufferEscapePairFree.
