comment out suitesparse and zlib until they're fixed

broken by aef65182d8e41f1b3cc99e04fb6eeeb1f4c67ff1.
require->include for "internal" loads. Also prepare for load->require.
Re-enable suitesparse and zlib tests

This reverts commit 23ac098d9ad19fb895e454e157bc53fd4ec01316.
Support Inf in bounds for linprog
remove Dimspec. fixes #1829
allow x[1] for scalar x, to be consistent with the treatment of 0-dimensional arrays [since ndims(x)==0 and length(x)==numel(x)==1]
Merge pull request #1843 from stevengj/refscalar

allow x[1] for scalar x
Update location for downloads
allow Real for indexes more thoroughly, eliminate Indices
fixes needed for expanded float indexing
fixing some cases of logical indexing too
small fix to bitarray logical indexing
Merge branch 'jb/realindex' of github.com:JuliaLang/julia
allow some more cases of tuple indexing
bitarray: revert specialized ref signature change
fix #1851
also fix peakflops() on 32-bit
Merge branch 'master' of github.com:JuliaLang/julia
readuntil() for any delim type
returns a string for Char delim, otherwise an array
readuntil(s, uint8('\n')) provides a way to read a line without an encoding check
streams are encouraged to provide an efficient readuntil(s, ::Uint8),
  then reading until ASCII delimiters is fast, leaving the encoding
  logic to higher-level layers in io.jl and string.jl.
for #1792
misc. cleanup and removing some unnecessary exports
Use SVD for computing the condition number of matrices (#1862)
Return Inf for singular matrices.
cond(A,2) also returns NaN for all zeros input.

To fix:
cond(A,p) returns Inf for all zeros input except when p = 2.
Close #1861
Use norm(A, :fro) instead of norm(A, "fro")
documentation for cond and norm
