Remove trailing whitespace in Makefiles.
Build system cleanup and improvement.

* Split out PG_CFLAGS and GLIB_CFLAGS so they're only calculated once.
* Rename all CFLAGS_* variables to *_CFLAGS.
* Split compile and link into CFLAGS and LDFLAGS respectively.
Makefile.conf : Restore COV_CFLAGS which got lost in cleanup.
updated the README file source tar file location.
fixed for unit test failure on pkgagent, because the test data is incorrect, should data insert into uploadtree_a.
Merge pull request #11 from erikd/master

Build system cleanup and improvements.
sqlCopy.c : Fix unsafe usage of strncat.

This was actually safe due to some pre-condition checking code, but gcc
4.9 was warning about it because it could detect the issue, but not the
pre-condion checking.
nomos : Use the return value of strerror_r() to avoid warning.
fixed for  #7941, mising rpm and fosslib libraries when do the pkgagent unit testing.
Merge pull request #12 from erikd/master

Merge pull request #13 from pguttmann/master

Modified environment logic. Fixes bug 7695
fixed for #7977, there are 2 solutions, one is like this checkin, annother is change all the places through replace ALL_CFLAGS with FO_LDFLAGS in the testing. if you think the 2nd one is better, please tell me.
Removed the epel repository installation during package install testing as it has been installed before the testing.
Change queries to use GetUploadtreeTableName and not hardcode "uploadtree".  This improves
performance on systems with large uploads and lots of jobs.
Remove upload_pk from queries to uploadtree_nnnn tables since it is redundant.  This also speeds up the query a bit.
remove upload_pk from query in countPlainFiles() when it is not needed (in uploadtree_nnnn tables).  This speeds up the query some.
