[PATCH v3 0/10] getcwd without PATH_MAX

["René Scharfe" <l.s.r@web.de>]

Paths longer than PATH_MAX can be created and used on at least on some
file systems.  Currently we use getcwd() generally with a PATH_MAX-
sized buffer.  This series adds two functions, strbuf_getcwd() and
xgetcwd(), then uses them to reduce the number of fixed-sized buffers
and to allow us to handle longer working directory paths.

Changes in v3:
  * all getcwd() calls are converted
  * the two strbuf_getcwd() examples from last round use xgetcwd()
    now, as suggested by Jeff
  * strbuf_add_absolute_path() is introduced

René Scharfe (10):
  strbuf: add strbuf_getcwd()
  unix-sockets: use strbuf_getcwd()
  setup: convert setup_git_directory_gently_1 et al. to strbuf
  abspath: use strbuf_getcwd() to remember original working directory
  abspath: convert real_path_internal() to strbuf
  wrapper: add xgetcwd()
  use xgetcwd() to get the current directory or die
  use xgetcwd() to set $GIT_DIR
  abspath: convert absolute_path() to strbuf
  use strbuf_add_absolute_path() to add absolute paths
