Daniel Dumitriu da8de6a647 Remove read constraint for directories on key path 
On Unix, do not check whether all directories on the path to storage_dir
are readable; in corporate environments this is often not the case.

Closes #28.

Christopher Wellons 32d4d99472 Properly terminate pinentry protocol (BYE) 
This isn't strictly necessary on unix-like systems since it will exit
when the pipes are closed. Unfortunately Windows isn't so nice and neat
and the program will remain open indefinitely even though its inputs and
outputs have been closed. So ask pinentry to terminate gracefully.

Christopher Wellons 7cc0e13f0a Allow Unicode passphrases on Windows 
This change uses ReadConsoleW() to read passphrase input. It converts
the passphrase from UTF-16 to UTF-8 before further processing. With
this, passphrase input is now consistent between platforms.

Currently Windows provides no options for reading keyboard input as
UTF-8, and it's certainly not supported by any of the various CRT
implementations. This is the only way to do it.

Christopher Wellons f7c4b6ba55 Support binary stdin/stdout on Windows 
It's now possible to pipe files over standard input and standard output
in Windows.

Christopher Wellons f01f732433 Fix number of command_names searched (fixes #18) 
The "help" subcommand was removed in 6d1407b, but the number of commands
searched was not updated. With this commit it always checks the right
number of command strings.

Christopher Wellons a38e5e3bb9 Add new keygen option: passphrase --repeats (-r) 
This option controls the number of repeated passphrase prompts when
deriving a secret key. It is convenient to set this to zero when relying
primarily on fingerprint verification. Alternatively, additional repeat
prompts may aid in memorization. The default value is 1.

Christopher Wellons ff83f9259e Drop use of custom integer names 
Just use the C99 integer names directly and document the ones that are
needed in a comment in config.h in case it's needed when porting.

Christopher Wellons 274b080e12 Fix indentation typo in cleanup_closed() 
Not sure how this mistake was made in the first place. Identified by a
dead code warning from Visual Studio 6.0.

Christopher Wellons a407afcdaf Add support for pinentry protocol 
This feature is now used by Emacs so that Emacs doesn't need to handle
the passphrase itself.

Christopher Wellons 514dc7d4dc Free all path strings before success exit 
This fixes all the valgrind complaints and properly frees all allocated
memory so long as the program exits successfully.

Christopher Wellons ab0ce78a00 Before mkdir(2), check if directory exists. 
On Cygwin, mkdir(2) reports EACCES if the directory exists but the
system call would have failed had it not existed. This is a little odd
since EEXIST would be a much more sensible error code, but this odd
behavior seems to be permitted by POSIX. If mkdir(2) fails, but the path
exists as a directory, then continue as normal.
