There is no longer any need to allocate and leak a `struct lock_file`.
Initialize it on the stack instead.
Before this patch, we set `lock = NULL` to signal that we have already
rolled back, and that we should not do any more work. We need to take
another approach now that we cannot assign NULL. We could, e.g., use
`is_lock_file_locked()`. But we already have another variable that we
could use instead, `found`. Its scope is only too small.
Bump `found` to the scope of the whole function and rearrange the "roll
back or write?"-checks to a straightforward if-else on `found`. This
also future-proves the code by making it obvious that we intend to take
exactly one of these paths.

Dynamic loading of DLL functions is duplicated in several places in Git
for Windows' source code.
This patch adds a pair of macros to simplify the process: the
DECLARE_PROC_ADDR(<dll>, <return-type>, <function-name>,
...<function-parameter-types>...) macro to be used at the beginning of a
code block, and the INIT_PROC_ADDR(<function-name>) macro to call before
using the declared function. The return value of the INIT_PROC_ADDR()
call has to be checked; If it is NULL, the function was not found in the
specified DLL.
Example:
DECLARE_PROC_ADDR(kernel32.dll, BOOL, CreateHardLinkW,
LPCWSTR, LPCWSTR, LPSECURITY_ATTRIBUTES);
if (!INIT_PROC_ADDR(CreateHardLinkW))
return error("Could not find CreateHardLinkW() function";
if (!CreateHardLinkW(source, target, NULL))
return error("could not create hardlink from %S to %S",
source, target);
return 0;
