* fixes#1823: xmlparse.cpp (expat) was included in mingw32 build when POCO_UNBUNDLED is set and caused 'XMLUtf8Encode undefined reference' error when building
* add cmake to the make dependencies list
* replace tabs by spaces:wq
* upgrade some broken packages
* correct some broken urls/checksums
* use secure urls where possible
* update PKGBUILD templates
* remove line-ending whitespace
* minor typos/fixes
Remaining md5sums either didn't download or
didn't pass checksum tests.
