c2e86addb8 Fix sparse warnings
Fix warnings from 'make check'.

 - These files don't include 'builtin.h' causing sparse to complain that
   cmd_* isn't declared:

   builtin/clone.c:364, builtin/fetch-pack.c:797,
   builtin/fmt-merge-msg.c:34, builtin/hash-object.c:78,

   builtin/remote-fd.c:53, builtin/reset.c:236, builtin/send-pack.c:384,
   builtin/unpack-file.c:25, builtin/var.c:75

 - These files have symbols which should be marked static since they're
   only file scope:

   submodule.c:12, diff.c:631, replace_object.c:92, submodule.c:13,
   submodule.c:14, trace.c:78, transport.c:195, transport-helper.c:79,

   url.c:129, url.c:136, thread-utils.c:21, thread-utils.c:48

 - These files redeclare symbols to be different types:

   builtin/index-pack.c:210, parse-options.c:564, parse-options.c:571,
   usage.c:49, usage.c:58, usage.c:63, usage.c:72

 - These files use a literal integer 0 when they really should use a NULL
   pointer:

   daemon.c:663, fast-import.c:2942, imap-send.c:1072, notes-merge.c:362

While we're in the area, clean up some unused #includes in builtin files
(mostly exec_cmd.h).

39bc5e4680 trace: factor out "do we want to trace" logic
As we add more tracing areas, this will avoid repeated code.

Technically, trace_printf already checks this and will avoid
printing if the trace key is not set. However, callers may
want to find out early whether or not tracing is enabled so
they can avoid doing work in the common non-trace case.

06796607ef trace: refactor to support multiple env variables
Right now you turn all tracing off and on with GIT_TRACE. To
support new types of tracing without forcing the user to see
all of them, we will soon support turning each tracing area
on with GIT_TRACE_*.

This patch lays the groundwork by providing an interface
which does not assume GIT_TRACE. However, we still maintain
the trace_printf interface so that existing callers do not
need to be refactored.

ebeb60900f strbuf: add strbuf_vaddf
In a variable-args function, the code for writing into a strbuf is
non-trivial. We ended up cutting and pasting it in several places
because there was no vprintf-style function for strbufs (which in turn
was held up by a lack of va_copy).

Now that we have a fallback va_copy, we can add strbuf_vaddf, the
strbuf equivalent of vsprintf. And we can clean up the cut and paste
mess.

e83c267f71 trace.c: ensure NULL is not passed to printf
GNU printf, and many others, will print the string "(null)" if a NULL
pointer is passed as the argument to a "%s" format specifier.  Some
implementations (like on Solaris) do not detect a NULL pointer and will
produce a segfault in this case.

So, fix this by ensuring that pointer variables do not contain the value
NULL.  Assign the string "(null)" to the variables are NULL.

and all the callers.

f141bd804d Handle broken vsnprintf implementations in strbuf
Solaris 9's vsnprintf implementation returns -1 if we pass it a
buffer of length 0.  The only way to get it to give us the actual
length necessary for the formatted string is to grow the buffer
out to have at least 1 byte available in the strbuf and then ask
it to compute the length.

If the available space is 0 I'm growing it out by 64 to ensure
we will get an accurate length estimate from all implementations.
Some callers may need to grow the strbuf again but 64 should be a
reasonable enough initial growth.

We also no longer silently fail to append to the string when we are
faced with a broken vsnprintf implementation.  On Solaris 9 this
silent failure caused me to no longer be able to execute "git clone"
as we tried to exec the empty string rather than "git-clone".

19247e5510 nfv?asprintf are broken without va_copy, workaround them.
* drop nfasprintf.
* move nfvasprintf into imap-send.c back, and let it work on a 8k buffer,
  and die() in case of overflow. It should be enough for imap commands, if
  someone cares about imap-send, he's welcomed to fix it properly.
* replace nfvasprintf use in merge-recursive with a copy of the strbuf_addf
  logic, it's one place, we'll live with it.
  To ease the change, output_buffer string list is replaced with a strbuf ;)
* rework trace.c to call vsnprintf itself.  It's used to format strerror()s
  and git command names, it should never be more than a few octets long, let
  it work on a 8k static buffer with vsnprintf or die loudly.

0746d19a82 git-branch, git-checkout: autosetup for remote branch tracking
In order to track and build on top of a branch 'topic' you track from
your upstream repository, you often would end up doing this sequence:

  git checkout -b mytopic origin/topic
  git config --add branch.mytopic.remote origin
  git config --add branch.mytopic.merge refs/heads/topic

This would first fork your own 'mytopic' branch from the 'topic'
branch you track from the 'origin' repository; then it would set up two
configuration variables so that 'git pull' without parameters does the
right thing while you are on your own 'mytopic' branch.

This commit adds a --track option to git-branch, so that "git
branch --track mytopic origin/topic" performs the latter two actions
when creating your 'mytopic' branch.

If the configuration variable branch.autosetupmerge is set to true, you
do not have to pass the --track option explicitly; further patches in
this series allow setting the variable with a "git remote add" option.
The configuration variable is off by default, and there is a --no-track
option to countermand it even if the variable is set.

e08140568a short i/o: clean up the naming for the write_{in,or}_xxx family
We recently introduced a write_in_full() which would either write
the specified object or emit an error message and fail.  In order
to fix the read side we now want to introduce a read_in_full()
but without an error emit.  This patch cleans up the naming
of this family of calls:

1) convert the existing write_or_whine() to write_or_whine_pipe()
   to better indicate its pipe specific nature,
2) convert the existing write_in_full() calls to write_or_whine()
   to better indicate its nature,
3) introduce a write_in_full() providing a write or fail semantic,
   and
4) convert write_or_whine() and write_or_whine_pipe() to use
   write_in_full().

6ce4e61f1b Trace into a file or an open fd and refactor tracing code.
If GIT_TRACE is set to an absolute path (starting with a
'/' character), we interpret this as a file path and we
trace into it.

Also if GIT_TRACE is set to an integer value greater than
1 and lower than 10, we interpret this as an open fd value
and we trace into it.

Note that this behavior is not compatible with the
previous one.

We also trace whole messages using one write(2) call to
make sure messages from processes do net get mixed up in
the middle.

This patch makes it possible to get trace information when
running "make test".
