Revert changes relative to lib/*.[ch] recent renaming
This reverts renaming and usage of lib/*.h header files done 28-12-2012, reverting 2 commits: f871de0... build: make use of 76 lib/*.h renamed files ffd8e12... build: rename 76 lib/*.h files This also reverts removal of redundant include guard (redundant thanks to changes in above commits) done 2-12-2013, reverting 1 commit: c087374... curl_setup.h: remove redundant include guard This also reverts renaming and usage of lib/*.c source files done 3-12-2013, reverting 3 commits: 13606bb... build: make use of 93 lib/*.c renamed files 5b6e792... build: rename 93 lib/*.c files 7d83dff... build: commit 13606bbfde follow-up 1 Start of related discussion thread: http://curl.haxx.se/mail/lib-2013-01/0012.html Asking for confirmation on pushing this revertion commit: http://curl.haxx.se/mail/lib-2013-01/0048.html Confirmation summary: http://curl.haxx.se/mail/lib-2013-01/0079.html NOTICE: The list of 2 files that have been modified by other intermixed commits, while renamed, and also by at least one of the 6 commits this one reverts follows below. These 2 files will exhibit a hole in history unless git's '--follow' option is used when viewing logs. lib/curl_imap.h lib/curl_smtp.h
