portable: configure: split out dependencies
Rather than assume all dependencies are required for all programs, split them out. This will make packaging easier, as well as splitting the code to use subprojects. Note that due to the use of config.h semantics, in most cases the got_compat.h header file is now at the top of the .c file it is included in, so that it can handle the system header inclusion properly.
fix off_t type mismatches
off_t is a signed type and depending on the platform, it can be "long" or "long long", so cast to long long for printf(). ok stsp
portable: add back sys/queue.h
Now that the handling of including sys/queue.h is better, there's no need to remove those lines from the source. Copy the location of those original sys/queue.h lines from upstream at the same line number, so as to avoid any conflicts in the future.
use random seeds for murmurhash2
change the three hardcoded seeds to fresh ones generated on demand via arc4random. Suggested/fixed by and ok stsp@

portable: add FreeBSD support
This adds the capability to compile got-portable on FreeBSD.
portable: initial Linux compilation
This commit modifies the GoT main branch to be able to compile it under linux.
fix seek to incorrect offset in the delta base when creating deltas
The stretchblk() function needs to compare data located after the block which has just been matched. However, upon entry it was resetting the file pointer of the delta base to the beginning(!) of the block. The other file is correctly positioned after the block. In many cases the data won't match and stretchblk() will not stretch the matched block. But when the data did happen to match this resulted in a bogus delta, and wrong file contents when the delta was applied. Fix this by setting the delta base file pointer to end of the block. Problem reported by naddy after our server refused a pack file which was sent by 'got send'. I could reproduce the issue by running the 'gotadmin pack' command on a copy of naddy's repository. ok naddy
allow the delta base file to lose its header between deltify_init and deltify
This simplifies pack file creation. A delta base could be read from a loose object, a packfile, or it might be available in a temporary file. All these cases can now be handled the same way. We may need to open, close, and re-open a given delta base multiple times while packing.
in addblk(), only read data into buffer1 if we will compare it to buffer2
