Jay Berkenbilt 4a1cce0a47 Reimplement name and number tree object helpers 
Create a computationally and memory efficient implementation of name
and number trees that does binary searches as intended by the data
structure rather than loading into a map, which can use a great deal
of memory and can be very slow.

Jay Berkenbilt 026330ebcd Make libtests depend on qpdf 
We need to run qpdf --show-crypto.

Jay Berkenbilt 4ccc8b1a44 Add ClosedFileInputSource 
ClosedFileInputSource is an input source that keeps the file closed
when not reading it.

Jay Berkenbilt 95ba7125ff Fix link order (fixes #176) 
Specify qpdf libraries before external ones.
Specify LDFLAGS before libraries.
This should eliminate remaining cases of qpdf builds favoring
previously installed versions.

Jay Berkenbilt 6299c64cf3 Use correct link directory order (fixes #158) 
Make sure to link from the source tree before linking from the system.
In many environments, this is necessary to allow a newly built qpdf to
link properly instead of trying to link or resolve libraries from an
older installed version.

Jay Berkenbilt 296b679d6e Implement findFirst and findLast in InputSource 
Preparing to refactor some pattern searching code to use these instead
of their own memchr loops. This should simplify the code that replaces
PCRE.

Jay Berkenbilt 5e3bad2f86 Refactor random data generation 
Add new RandomDataProvider object and implement existing random number
generation in terms of that.  This enables end users to supply their
own random data providers.
