[Bruce Dubbs]

New minor version.

11.5.0: release

• Mostly this is changes to the private API, performance enhancements, code cleanup, and reformatting to 100 columns instead of 80. For qpdf development, we are starting to use JetBrains CLion, so a lot of the changes are moving us toward a cleaner development experience in that environment.

• Bug fix: when a the same page is copied multiple times, copy the annotations rather than having multiple pages share an annotation object.

• Add "FUTURE" build option for enabling experimental APIs. Do not package qpdf built with the FUTURE option as there are no binary compatibility or even source compatibility guarantees. The option is intended for developers who want to ensure that future potentially breaking changes are compatible with their code or provide feedback on upcoming changes. At present, the only feature enabled by FUTURE is a move constructor for QPDFObjectHandle. While this shouldn't break any code, it would change details about how many copies of a specific QPDFObjectHandle were in existence, so it could potentially break code that was relying on internal shared pointer reference counts.

• Add new method Buffer::copy and deprecate Buffer copy constructor and assignment operator. Buffer copy operations are expensive as they always involve copying the buffer content. Use "buffer2 = buffer1.copy();" or "Buffer buffer2{buffer1.copy()};" to make it explicit that copying is intended.
