base/str.cc:
Make some fixes for the to_number function.
Fix overflow calculation for maximum decimal value.
(Note: minimum decimal value for signed numbers does not
work correctly, e.g. it will overflow on -128 for a signed char
though -127 will work)
Fix overflow calculation for hex values being converted into
signed types
Fix up the debugging stuff a little to make sure the values are
always printed as numbers.
test/strnumtest.cc:
using namespace std for g++ 3
