Import "glob" and "getcwd" modules from gnulib 

These two modules are necessary because of the rework that will be
done in the "change directory" logic on GDB/gdbserver in the next
commits.

First, we will get rid of the "gdb_dirbuf" global variable and instead
rely on the fact that "getcwd (NULL, 0)", which is a GNU extension,
returns a heap-allocated string with the necessary bytes to hold the
full path.  This is a good practice not only because globals are not
ideal but also because there is no good way to know beforehand the
size of the full pathname allowed in the filesystem ("PATH_MAX" is not
portable and does not reflect all the possible filesystems out there).

We will also have a way to "cd" to a directory also on gdbserver, but
in order to do that uniformly, there must be a way to do tilde
expansion on directories provided by the user.  Currently, GDB uses
"tilde_expand" from readline to do that, but gdbserver doesn't link
against readline and therefore cannot use this function.  The solution
is to use "glob" instead, which can perform tilde expansion as a GNU
extension.  Therefore, we need gnulib's version of "glob".

A special note is necessary for gdb/ser-tcp.c.  It defines "close" as
"closesocket" on Win32 targets.  If we leave the code as is, this
would conflict with gnulib's definition of "close".  Therefore, in
order to keep the same code path from before this import, I decided to
"#undef close" first, and then let the original (re)definition of it
take place.

Restrictions on *_RANGE_OVERFLOW macros:
These macros do not check for all possible numerical problems or
undefined or unspecified behavior: they do not check for division
by zero, for bad shift counts, or for shifting negative numbers.
These macros may evaluate their arguments zero or multiple times,
so the arguments should not have side effects. The arithmetic
arguments (including the MIN and MAX arguments) must be of the same
integer type after the usual arithmetic conversions, and the type
must have minimum value MIN and maximum MAX. Unsigned types should
use a zero MIN of the proper type.
These macros are tuned for constant MIN and MAX. For commutative

/* Check for integer overflow, and report low order bits of answer.
The INT_<op>_OVERFLOW macros return 1 if the corresponding C operators
might not yield numerically correct answers due to arithmetic overflow.
The INT_<op>_WRAPV macros also store the low-order bits of the answer.
These macros work correctly on all known practical hosts, and do not rely
on undefined behavior due to signed arithmetic overflow.
Example usage, assuming A and B are long int:
if (INT_MULTIPLY_OVERFLOW (a, b))
printf ("result would overflow\n");
else
printf ("result is %ld (no overflow)\n", a * b);
Example usage with WRAPV flavor:
long int result;
bool overflow = INT_MULTIPLY_WRAPV (a, b, &result);
printf ("result is %ld (%s)\n", result,
overflow ? "after overflow" : "no overflow");
Restrictions on these macros:
These macros do not check for all possible numerical problems or
undefined or unspecified behavior: they do not check for division
by zero, for bad shift counts, or for shifting negative numbers.
These macros may evaluate their arguments zero or multiple times, so the
arguments should not have side effects.
The WRAPV macros are not constant expressions. They support only
+, binary -, and *. The result type must be signed.
These macros are tuned for their last argument being a constant.
Return 1 if the integer expressions A * B, A - B, -A, A * B, A / B,
A % B, and A << B would overflow, respectively. */

bytes in the longword in question are equal to c. We first use an xor
with repeated_c. This reduces the task to testing whether *any of the
four* bytes in longword1 is zero.
We compute tmp =
((longword1 - repeated_one) & ~longword1) & (repeated_one << 7).
That is, we perform the following operations:
1. Subtract repeated_one.
2. & ~longword1.
3. & a mask consisting of 0x80 in every byte.
Consider what happens in each byte:
- If a byte of longword1 is zero, step 1 and 2 transform it into 0xff,
and step 3 transforms it into 0x80. A carry can also be propagated
to more significant bytes.
- If a byte of longword1 is nonzero, let its lowest 1 bit be at
position k (0 <= k <= 7); so the lowest k bits are 0. After step 1,
the byte ends in a single bit of value 0 and k bits of value 1.
After step 2, the result is just k bits of value 1: 2^k - 1. After
step 3, the result is 0. And no carry is produced.
So, if longword1 has only non-zero bytes, tmp is zero.
Whereas if longword1 has a zero byte, call j the position of the least
significant zero byte. Then the result has a zero at positions 0, ...,
j-1 and a 0x80 at position j. We cannot predict the result at the more
significant bytes (positions j+1..3), but it does not matter since we
already have a non-zero bit at position 8*j+7.
So, the test whether any byte in longword1 is zero is equivalent to
testing whether tmp is nonzero. */
