add 'git credential' plumbing command The credential API is in C, and not available to scripting languages. Expose the functionalities of the API by wrapping them into a new plumbing command "git credentials". In other words, replace the internal "test-credential" by an official Git command.

#include "git-compat-util.h"
introduce credentials API There are a few places in git that need to get a username and password credential from the user; the most notable one is HTTP authentication for smart-http pushing. Right now the only choices for providing credentials are to put them plaintext into your ~/.netrc, or to have git prompt you (either on the terminal or via an askpass program). The former is not very secure, and the latter is not very convenient. Unfortunately, there is no "always best" solution for password management. The details will depend on the tradeoff you want between security and convenience, as well as how git can integrate with other security systems (e.g., many operating systems provide a keychain or password wallet for single sign-on). This patch provides an abstract notion of credentials as a data item, and provides three basic operations: - fill (i.e., acquire from external storage or from the user) - approve (mark a credential as "working" for further storage) - reject (mark a credential as "not working", so it can be removed from storage) These operations can be backed by external helper processes that interact with system- or user-specific secure storage.

git credential fill: output the whole 'struct credential' Instead of outputing only the username and password, print all the attributes, even those that already appeared in the input. This is closer to what the C API does, and allows one to take the exact output of "git credential fill" as input to "git credential approve" or "git credential reject".
