	[linux] fix hash functions used for finding local tcp/udp IPCs
	There were typos in the code calculating hash values. The typos might
	break the flatness of hashtables where the endpoint information about
	locally used tcp/udp was stored. Theoretically, this fix may improve
	the performance of lsof with [+|-]E option.
	Inspired by the issue #206 reported by Tomasz Kłoczko (@kloczek).

	[darwin] fix build with -fno-common (Cfp redefinition)
	gcc-10 and llvm-11 changed the default from -fcommon to -fno-common:
	https://gcc.gnu.org/PR85678
	As a result build fails as:

		duplicate symbol '_Cfp' in: ddev.o dfile.o

	Cfp is already explicitly defined in dstore.c. The change turns
	header definition into declaration.
	Provided by Sergei Trofimovich (@trofi) in #221. The same fix is
	applied to libproc backend by Jiajie Chen (@jiegec) in #226.
