** Counted, reusable memory buffer.
**
** A buffer is an allocated bit of memory with a known size and a separate
** data length. It's intended to store strings and can be reused repeatedly
** to minimize the number of memory allocations. Buffers increase in
** increments of 1K.
**
** A buffer contains a notion of the data that's been used and the data
** that's been left, used when the buffer is an I/O buffer where lots of data
** is buffered and then slowly processed out of the buffer. The total length
** of the data is used + left. If a buffer is just used to store some data,
** used can be set to 0 and left stores the length of the data.

** Generic hash table interface.
**
** Written by Russ Allbery <rra@stanford.edu>
** This work is hereby placed in the public domain by its author.
**
** A hash table takes a hash function that acts on keys, a function to
** extract the key from a data item stored in a hash, a function that takes
** a key and a data item and returns true if the key matches, and a
** function to be called on any data item being deleted from the hash.
**
** hash_create creates a hash and hash_free frees all the space allocated
** by one. hash_insert, hash_replace, and hash_delete modify it, and
** hash_lookup extracts values. hash_traverse can be used to walk the
** hash, and hash_count returns the number of elements currently stored in
** the hash. hash_searches, hash_collisions, and hash_expansions extract
** performance and debugging statistics.

** convenient way of managing a list of strings, as well as a reasonable
** output data structure for functions that split up a string. There are
** two basic types of vectors, regular vectors (in which case strings are

** cvectors or const vectors (where each pointer is a const char * to some
** external string that isn't freed when the vector is freed).
**
** There are two interfaces here, one for vectors and one for cvectors,

**
** Message and error reporting (possibly fatal).
**
** Usage:
**
** extern int cleanup(void);
** extern void log(int, const char *, va_list, int);
**
** message_fatal_cleanup = cleanup;
** message_program_name = argv[0];
**
** warn("Something horrible happened at %lu", time);
** syswarn("Couldn't unlink temporary file %s", tmpfile);
**
** die("Something fatal happened at %lu", time);
** sysdie("open of %s failed", filename);
**
** debug("Some debugging message about %s", string);
** trace(TRACE_PROGRAM, "Program trace output");
** notice("Informational notices");
**
** message_handlers_warn(1, log);
** warn("This now goes through our log function");
**
** These functions implement message reporting through user-configurable
** handler functions. debug() only does something if DEBUG is defined,
** trace() supports sending trace messages in one of a number of configurable
** classes of traces so that they can be turned on or off independently, and
** notice() and warn() just output messages as configured. die() similarly
** outputs a message but then exits, normally with a status of 1.
**
** The sys* versions do the same, but append a colon, a space, and the
** results of strerror(errno) to the end of the message. All functions
** accept printf-style formatting strings and arguments.
**
** If message_fatal_cleanup is non-NULL, it is called before exit by die and
** sysdie and its return value is used as the argument to exit. It is a
** pointer to a function taking no arguments and returning an int, and can be
** used to call cleanup functions or to exit in some alternate fashion (such
** as by calling _exit).
**
** If message_program_name is non-NULL, the string it points to, followed by
** a colon and a space, is prepended to all error messages logged through the
** message_log_stdout and message_log_stderr message handlers (the former is
** the default for notice, and the latter is the default for warn and die).
**
** Honoring error_program_name and printing to stderr is just the default
** handler; with message_handlers_* the handlers for any message function can
** be changed. By default, notice prints to stdout, warn and die print to
** stderr, and the others don't do anything at all. These functions take a
** count of handlers and then that many function pointers, each one to a
** function that takes a message length (the number of characters snprintf
** generates given the format and arguments), a format, an argument list as a
** va_list, and the applicable errno value (if any).

/* $Id: xmalloc.c 5381 2002-03-31 22:35:47Z rra $
**
** malloc routines with failure handling.
**
** Usage:
**
** extern xmalloc_handler_t memory_error;
** extern const char *string;
** char *buffer;
**
** xmalloc_error_handler = memory_error;
** buffer = xmalloc(1024);
** xrealloc(buffer, 2048);
** free(buffer);
** buffer = xcalloc(1024);
** free(buffer);
** buffer = xstrdup(string);
** free(buffer);
** buffer = xstrndup(string, 25);
**
** xmalloc, xcalloc, xrealloc, and xstrdup behave exactly like their C
** library counterparts without the leading x except that they will never
** return NULL. Instead, on error, they call xmalloc_error_handler,
** passing it the name of the function whose memory allocation failed, the
** amount of the allocation, and the file and line number where the
** allocation function was invoked (from __FILE__ and __LINE__). This
** function may do whatever it wishes, such as some action to free up
** memory or a call to sleep to hope that system resources return. If the
** handler returns, the interrupted memory allocation function will try its
** allocation again (calling the handler again if it still fails).
**
** xstrndup behaves like xstrdup but only copies the given number of
** characters. It allocates an additional byte over its second argument and
** always nul-terminates the string.
**
** The default error handler, if none is set by the caller, prints an error
** message to stderr and exits with exit status 1. An error handler must
** take a const char * (function name), size_t (bytes allocated), const
** char * (file), and int (line).
**
** xmalloc will return a pointer to a valid memory region on an xmalloc of 0
** bytes, ensuring this by allocating space for one character instead of 0
** bytes.
**
** The functions defined here are actually x_malloc, x_realloc, etc. The
** header file defines macros named xmalloc, etc. that pass the file name
** and line number to these functions.
